OWC SSD Firmware Updated

Good news! After nearly two months of testing, we’re pleased to announce we’ve approved a new updated SandForce firmware version for our SSDs.

Now every drive that ships from OWC as of last Friday will have that new firmware which 100% resolves any hibernation issue you may have experienced.

While this issue only affected around 10% of all our SSD customers, we’re 100% committed to everyone’s satisfaction.

So, you can get this new firmware update in one of two ways:

Visit our firmware update page

or you can contact us to arrange sending your drive to us and we’ll flash update the drive for you.

Now, let me head you off at the pass….we do not have a Mac based firmware updater yet. While SandForce initially indicated they were going to create a universal updater, we feel you have waited patiently long enough and have taken up the baton on this ourselves. We’re working diligently on this and will let you know when we have something ready.

OWC Note: As there has been some confusion between Sleep & Hibernation…

There have been two SandForce-related issues with some of these drives, both of which can be corrected at this time.

For those with hibernation issues, this firmware corrects those issues.
For those with sleep issues there is a physical parameter change that OWC can do in-house to correct.

Please call our Technical Support team at 1 (800) 275-4576 for further assistance with either issue.

UPDATE 4/1/11: The firmware UPDATER TOOL itself has been determined to be incompatible with Mac Pro model ID MacPro1,1; MacPro 2,1; MacPro 3,1

To determine your Model ID visit:

If you do not have access to another machine, you have the option of having us update the firmware on your drive OR choosing not to update the firmware. Please note that the primary update to this latest firmware revision corrected a hibernation issue for MacBook and MacBook Pro owners. Hibernation is not an Apple supported mode with Mac Pro/iMac/mini machines and therefore the firmware update is not an absolute requirement for Mac Pro, iMac, and/or mini owners. Should you wish for us to update the firmware, please contact our Customer Service department at 800-275-4576

  • Hello
    I’m trying to update the firmware FW 3.3.2 via bootcamp and the process ends fine, no errors, but the version of firmware does not change. I have a mac mini server 2011. What is the matter?

  • when will there be a mac firmware update out? i have a owc ssd and a data doubler in. and i do not have windows on my mac…? i had to take out the ssd put my stock hdd and put back in my optical drive. extremely frustrated. don’t understand why there is not a mac version. thats like my ford dealer telling me i have to go to chevy to get my car fixed. have a 300 dollar paperweight. please help me.

      • Hi! When will there be a update for the 6G Mercury Extreme pro 240 GB? I just purchased it, and installed it on my Mac Pro 5,1 I made a Carbon Clone Copy of my OS to it and it worked fine for a day, then I left it over night and now it won’t boot from the SSD, the computer won’t even recognize it, but some other times all of a sudden it appears on a boot from my original HD and I am able to boot from it, I can even shot the computer down and wait a few minutes and boot from it again, but if I leave the computer shutdown over night then the same thing the computer won’t even see the drive and it won’t boot from it. The firmware is the 830ABBF0 that the drive came with.

        • We don’t currently have a “schedule” for firmware updates to the drive, as these are mostly determined by updates to the SandForce processor firmware.

          However, from the sounds of it, the problem you’re describing has very little, if anything to do with Firmware. It sounds like there’s the possibility that something happened with the clone, and the OS on that drive isn’t “blessed.”

          I will suggest you take the following actions to try and resolve this problem

          1.) Boot to your original drive and Erase the SSD using Disk Utility.
          2.) Perform a clean installation of OSX on your SSD.
          3.) Use Migration Assistant, rather than a clone, to bring your data from your original drive over to your SSD.

          If, you are still having trouble getting your Mac Pro to boot to your SSD, you’ll want to contact our Technical Support center. One of our representatives will be glad to help you.

      • @OWC Grant

        I think the reason Daniel Ryan is frustrated is because “i had to take out the ssd put my stock hdd and put back in my optical drive.”

        The current Mac updater requires that the optical drive be installed in the computer to run the firmware update. However, many of us have removed the optical drives and purchased the data doubler.

        Are Mac customers without Bootcamp installed expected to swap the optical and hard drives in and out every time a new firmware update comes out?

  • I am deeply, deeply frustrated with OWC at this point, and judging by the good deal of chatter on the internet about the sleep issues with the SSDs, I am not alone. Customers have had these drives installed at real expense, only to find that they cripple their computers. I feel pretty sure that there are many other people as angered as I am that OWC did not proactively contact them to let them know this might be an issue for their machine, thus letting them waste huge amounts of time wondering what the heck is going on with their machines in the hope that there wouldn’t be a problem. There is a problem.

    I wrote to technical support in real exasperation, having clean-installed, looked for externals causing the sleep-hang issue, and wasted many hours doing so. When I enquired why OWC had not proactively contacted customers who _might_ be experiencing this issue, to save them all the wasted time, I was told “if we had any idea that these issues were occurring, of course we would have contacted you.” When I pointed out this very page with its long list of customer comments, which reveal that such a response was—at the least—disingenuous, and OWC had long known it was a potential issue for my computer, the response was: “I apologize.” Hmmm.

    The proposed solution? To send in the computer, at my substantial expense and with a narrow window for this return to happen, to fix a problem that OWC created in my brand new computer by installing hardware that crippled the machine. This is not acceptable, asking me to pay much more money to get what I should have received in the first place. Can you imagine buying a new car that has a recall issue, and having it handled in the way OWC is handling this? Don’t let potentially affected customers know, wait till the problem causes real issues, then soft-soap it, and have the customers pay for bringing in the machine to get it fixed?

    OWC should be offering free shipping both ways to fix this problem, and they should also be offering a very serious apology to their customers, so that they do not become former customers, or still worse and more likely, angered former customers who spread the word. Do they or do they not stand behind their work? Look at this list of people who are waiting for OWC to get serious. The way things stand now, there are real credibility problems that are not going to go away.

    • Even though the Blog team members are not directly in the Customer Service or Tech Support departments here at OWC, this comment certainly caught our eye and we made sure a variety of appropriate staff members were notified.

      As it turns out, the problem you describe with your iMac Turnkey Upgrade service from us is *not* due to the firmware. Rather, there is another setting that needs to be adjusted on the drive itself. There were very few systems this setting affected and again, it was an oversight on our behalf that you weren’t contacted proactively. We do apologize for this situation as we truly do exist to serve the customer here.

      A Customer Service representative should be reaching out to you to help get things resolved to your complete satisfaction.

      • @OWC Chris S.

        “Rather, there is another setting that needs to be adjusted on the drive itself.”

        Chris, can you elaborate on what this setting is that needs to be adjusted?

        • As I understood the explanation from our development team, there was a parameter outside the SandForce firmware that needed to be adjusted in-house. I can’t comment any further on it, and it’s a moot point now – it was a small run of iMac upgrades where the setting needed changing on the drives. At this point in time, all new drives work normally.

  • Hi
    I’ve been having a problem with my SSD 6g 240 GB on macbook pro 6,2 since my upgrade to Lion. The problem consists of haphazard hang ups that occur up to 3 times per hour rendering my macbook unusuable. The apple store checked the system and said that the problem is most probably occuring from the SSD drive and advised me to update the hard disk’s firmware.
    Therefore, i downloaded the mac firmware update tool and burned it to a DVD. It shows a couple of errors while loading but ends up loading fine. The problem is that after searching the system the updater does not find any attached SSD drives. The SSD drive is installed in the old hard disks place internally and is normally deteced in mac os lion.
    I tried a PRAM reset by holding command+option+P+R but to no avail the problem still exists.

    I am stuck and dont know what to do .. my system is unusuable in this state and i’m really regretting having bought this SSD drive.

    Hope anyone could help find a solution to help the updater find the SSD drive

    • Please contact our Technical Support Team and they would be happy to assist in troubleshooting the firmware update. In the meantime, I’d suggest trying the download again from scratch – if you got errors while loading, it may be that the original download was corrupted or incomplete.

      • Hi Christopher

        Unfortunately i haven’t yet found a way to update my drive. I kinda gave up on it ! I installed Windows 7 on Bootcamp and tried to update the drive from there. The updater finally detects the drive and actually succeeds in updating it. The strange part is that after i restart into mac and check the firmware version on the drive, i find the same version as before therefore nothing has been done.

        So, i decided to give up until OWC do a better job with their updater.

        Hope that can help in some way

        • I noticed you said you had a 6G drive. There hasn’t been a newer firmware revision for the 6G drives since we’ve introduced them. We have the utility available for when the next revision comes out. Your results with the 6G updater would have been normal then, as it only shows drives with an older version of the firmware. As for the Windows updater – I wouldn’t be surprised if it didn’t just install the same version of the firmware over the old one – after all, it’s the latest revision.

          But I’d like to go back further a little, to your original problem. While I can’t say for sure what’s causing the problems you’re having, I’m seriously doubting that it’s a firmware problem with the SSD – we’d have heard a lot more about this if it were a firmware problem.

          The Apple Store has long had the habit of blaming all sorts of problems on third-party upgrades. That doesn’t necessarily mean it is so; one of my favorite customer stories from my Tech Support days is the one where Apple claimed that third party memory was responsible for the hinges on a PowerBook G4 breaking. Them recommending you “update the firmware on the SSD,” seems more to me a case of throwing ideas at the wall to see what sticks.

          My gut instinct says to erase the hard drive and perform a fresh install of your OS (aka “Nuke & Pave”) to see if the problem continues. SInce you mentioned you’re running Lion, this may be a little more involved, as you’ll first want to create a bootable installer disk. There are plenty of instructions how to do this – a quick Google search of “InstallESD.dmg” should bring up a number of how-tos.

          Once you’ve done this, clone your SSD to an external drive, erase the SSD and Install Lion using the disc you created, then use Migration Assistant to bring your data back over from your external drive.

          Outside that, I will echo OWC Michael’s sentiments; contact our Technical Support staff by phone (800.275.4576; International: 815.338.8685), via email or through Live Chat and they will be happy to help you.

  • Hi everybody…

    I just installed my brand new Owc Mercury Extreme Pro 6G 120GB to my Macbook Pro and it works 3 days without problem and then freeze after sleep.

    I forced shut down and then MBP won’t recognise my hdd anymore. After that i download Owc July 25, 2011 firmware update and i did everything same as instructions but also firmware update program didn’t recognise my hdd.

    After that i replaced Owc Mercury Extreme Pro 6G 120GB with my old HDD and my MBP recognise old one.

    I need help urgently…

    Best regards,

    • @Rasiha this sounds like similar behavior I’m experiencing on a 2010 Macbook Pro 15″. I originally purchased an EXTREME™ Pro 6G 240GB drive and installed it into my Macbook Pro. I tried a bunch of things and was unable to get the system to recognize the drive. I even put it into my windows PC laptop and windows was unable to see the drive. Thinking the drive was bad, I RMA’d the drive and got a replacement.

      After installing the replacement, I saw the same behavior: my MBP was unable to recognize the drive. On a whim, I tried booting off an external drive with Snow Leopard installed. Magically, the drive appeared and continued to appear acrosss reboots! I figured I’d fixed it, and I formatted the drive and installed Lion using the Lion install CD I burned myself. Lion seemed to work fine for a few days.

      A couple days later, I had to install bootcamp on the Apple Seagate internal drive in the MBP, which required me to reinstall my optical drive (thus temporarily removing the SSD while bootcamp installed off the optical drive). After a flawless bootcamp install, I removed the optical drive and reinstalled the SSD. The SSD drive was unable to be recognized by the MBP again! After rebooting a couple times and booting off a couple different sources (external drive and install CD rom), the SSD magically appeared again.

      I have no idea why the drive is not visible to the MBP after physically installing it, but it seems like a random combination of rebooting and booting off other media made it reappear both times for me.

      However, not all is well. I’m now getting the spinning beach ball when I try to resume from sleep in Lion (on the SSD) and I’m trying to figure out how to fix that issue…

  • I’ve just updated firmware in my drive, using OS X
    it took me a while and I want to share my experience so maybe OWC can update instructions:

    I’ve tried to make a bootable SD card with the image but it doesnt work
    the same with bootable external disk partitions
    only actually burning a DVD I was able to boot the firmware update system.

    Hope this update fixes the issues on drive

  • how to know if I should upgrade the firmware ?

    My OWC is :

    Modell: OWC Mercury EXTREME Pro 6G SSD
    Revision: 320ABBF0
    S/N: MX6G24011E29E0251

    I can update from windows 7 booted from USB stick ?


  • Since many have been asking, we are VERY close to completing the Mac version of the firmware updater. Stay tuned to the OWC Blog as an announcement regarding such should be made within the next two weeks.

  • How far is the Mac based firmware updater development and is it true, that for the sleep problem (in Mac mini), a coming firmware update will solve this and hence a SSD purchased mid January will not need to be returned for a physical parameter change ?

  • Well, it has been over a year since OWC promised a Mac version of the installer. I know they write “we’re working diligently on this and will let you know when we have something ready” but after so long and several PC updates … hope for a Mac updater seems about gone. No ETA, no Mac updater even on the horizon, no timeline from OWC … by the time the updater is out, most likely SSD drives will have been replaced by the next drive technology and OWC will drop support (as they mostly have for PATA). So OWC, tell me different … no vague promises of future glory … where’s the Mac updater release at really?

  • Where is the answer to the several reports of “Download firmware Failed.”? You only mention about MacPro versions, but what about MacBook Pro?

  • Just recently got a MBP 17″ and the 240GB Extreme SSD.
    Installed it today on OS X 10.6.8, and run the AJA System test.
    What I first notice is that running this is the write tests pause very frequently, and are bursty.
    Read tests are around 490 MB/s.

    Pretty disappointed in the write tests, not sure if it is the MBP or the SSD.

    Where does one find the firmware version of the SSD ? Is that the revision under the
    OWC Mercury EXTREME PRO 6G SSD, which it says 319ABBF0 ?
    If it’s not the latest firmware, why would OWC ship the current EXTREME SSD’s with older firmware ?

    • The firmware identifier for the 6G line of OWC SSDs is 319ABBF0. This post that you’re commenting on was written before the 6G models were even released. There has been no updates to firmware for the 6G SSDs since their release so you do have the current firmware.

      It sounds as if you’re running into the issues due to installing a 6G drive into a 2011 17″ MacBook Pro. This has been an issue with that machine itself – for more information please read our blog post MacBook Pro 2011 Models and SATA 3.0 (6.0Gb/s) – Update – 5/27/2011

  • Argh!The updater will not recognize the SSD drive on my laptop, under Windows 7!!! I followed your tech’s suggestion, and I moved the SSD from the Drive Doubler to the main drive bay. I HATE it when such advice is spurious and a waste of time!

    Meanwhile, I cannot find any suggestions to solve this problem. Surely, there are others who find the update does not see the SSD drive?

    Yes, I’m running Windows from the second internal hard drive.


    • We were looking into this with the engineers and it still must come back to the machine and/or OS install procedure. I’m forwarding your name to our TS dept and a senior technician will contact you directly to walk you thru the firmware update.
      To answer your one question though, no, we have not had users experience the update not “seeing” the SSD…

  • Hi there,

    I just purchased 2 Mercury Pro SSD. On the label of the drive, it shows that Firmware Rev: 3.6.1. Is that the latest firmware up to date? Or I have to run the firmware update to 360A13F0?

        • I should clarify, depending on the particular drive you have there are two versions of the firmware update – both are the latest for specific drive models. They are 360A13F0 and 361A13F0 (listed on the drive labels as 3.6.0 or 3.6.1). There are no compatibility or functionality changes between the two versions.

      • I have own a Mercury Extreme Pro with FW 360A13F0. It shows the well known issue of the never ending turning beachball after a wake up out of sleep mode.

        Today, I installed Mac OS 10.7 (Lion), and hoped anything would change. Unfortunately this is not the case.
        Is OWC still seriously investigating in this issue? An availability date for the fix would be much appreciated.

        • I have the same problem and have had since I bought the drive in November of 2010. revision 340A13F0. I was hoping the issue had been fixed with Lion, but no. I can put the drive to sleep manually with no issue, but if I use the energy saver to put it to sleep the finder freezes on waking and the spinning beach ball of boring crash hell happens with a need for a hard restart. Beyond that the drive works great, but who wants to have to do workarounds? The drive is in my MacPro 3,1

    • A Mac version of the updater is still being worked on. We will announce it here on the blog as soon as it is available.

      • Is there an eta for this? As what looks to be your target audience, it’s sure a shame that there isn’t a mac version to update the firmware.

      • yes please hurry up with the mac firmware updater.. I’ve had my ssd for over 3 months … the windows option is a bit too complicated for a average user like myself… and now my SSD has died…. and needs a fresh install yet I cant connect to it for more than 2 mins.. grr…

        • I agree. i had to take my ssd out of my laptop because i can’t wake back up from sleep. tired of having to hard boot 15 times a day. i feel like i wasted 300 dollars on this drive and data doubler. disappointed.

      • It’s been a while since this update is available for windows … I have this annoying hibernation problem …

        I’ve always like OWC support, but right now I feel left in the dark

        What is going on ?

  • I have a Macbook Pro 2011 15″. I have the 240 SSD Extreme. It was having problems with sleep (beechball) when I had it in the OPTIBAY and a regular drive in the standard bay. I swapped the position and the problem continues. I am trying to determine if there is still a problem/solution to this and as I order the drive less than 1 month ago can I test for this parameter check and then send in the drive? Also has anyone with a Macbook Pro 2011 done this and solved the sleep problems?

    Thanks, Russ

    • i have a 15 inch 2011 macbook pro, im having the same issue. when it come up from sleep i have no wireless connection then i get the beachball freezeup

  • when will there be a mac firmware update out? i have a owc ssd and a data doubler in. and i do not have windows on my mac.

  • I upgraded to firmware 360 but still have problems with SLEEP.

    what else can be done? Return the ssd and if yes how, I live in Mexico.

    • Hola Carlos yo estoy en la misma situación, tengo una MacBookPro6,2 y simplemente desactivé el sleep automático y ya no he tenido broncas, lo unico molesto es que tendrás que poner a dormir a tu MBP manualmente…


      Editor’s rough translation: Hello Carlos I am in the same situation, have a MacBookPro6,2 and I simply deactivated automatic sleep and no longer I have had any problems. The only annoying thing is that you will have to put to manually sleep your MBP…

  • Trying in BootCamp Win7 64-bits but after cliking update the computer freezes.

    It is a MBP 13″ 8.1 (2011)

    Frustating, Can we expect something soon?

    Agree with those comments about not putting this in the firmware page and hiding them here.


      • Please add this model iMac to the incompatible list:

        – 27″ iMac, 2.66GHz i5 CPU, 8 megs RAM, 120 gig Mercury Pro Extreme SSD, firmware version 320A13F0.

        Running Windows 7 Ultimate x64 under Boot Camp. I get the same exact results as Carmatana. The updater works fine until I get to the final dialog box about backing up the system,. As soon as I hit “OK”, the entire machine locks up. I have rebooted, made sure I was running the program in Admin mode, reset the PRAM and SMC.

        Please let us know if/when an new Updater that works will be released.


  • Hi everybody

    For all those Apple-Users how are not able to update the firmware on a OWC Mercury Extreme PRO / PRO RE SSD I have found a “solution”, unfortunately you need a PC.

    Requirements: OWC SSD, PC (no OS required), Win7 install DVD (32bit), USB-Stick (FAT32).

    1. Download the firmware zip-file and copy the content directly in the volume of the usb-stick
    2. Remove the SSD from your Mac
    3. Connect the SSD to the internal SATA adapter on the PC
    4. Connect the USB-Stick on a free USB-Port on the PC
    5. Put the Win7 Install DVD in the DVD drive on the PC
    6. Power on your PC and boot from DVD
    7. Chose “Repair your computer”.
    8. Navigate to “Command prompt”
    9. Type “diskpart”
    10. Type “list volumes” and verify which letter is assigned to your USB-Stick, after that, type “exit”
    11. Type the “Letter from your usb-stick:”
    12. Type “ssdupdate” and the application will start.
    13. Navigate to the pkg-file and select your drive (it will takes some seconds)
    14. Download the firmware to the drive
    15. Reboot and verify again.

    I hope this will help (for my part, it did).

    Best regards’


  • I was having sleep issues with my MacBook Pro following a Lion installation and thought it was related to the SSD drive. Turns out it was the result of a kernel extension left behind by DisplayPad. Thought I’d pass it along in case it helped anyone. Here’s the info from the developers:

    There is no way to uninstall automatically. You can manually uninstall by doing the following:
    1) Disable DisplayPad from launching on Startup
    2) Delete /System/Library/Extensions/SSFramebuffer.kext/
    3) Reboot

  • My drive have no sleep issue and is using the 360 version. Only recommendation is to go to “energy” settings and uncheck “power hdd down when ever possible” in both battery and power adaptor and see if it fixes it.

    I did many test yesterday night because of the sleep problems. I found a solution for now. In Energy Saving, UnCheck Put the hardDisk to Sleep when possible and also install PLEASESLEEP (take controls over the OS X Energy Saver and force a Menu Click Sleep). I have version 343 and could not udpate to 360 (Crashing while Downloading sectors). So far , no more sleep hang(beachball)!

    • I updated to 360 after much trouble and almost bricked my SSD… Dismayed to find that with new firmware and 2011 MBP, waking up from sleep is beach balling need to shutdown forcefully.

    • Dear Eric, I can confirm that your solution to the SLEEP problem works correctly. While OWC works on solving the problem for us not being able to upgrade the SSD firmware, I will use PLEASESLEEP. Thank you for the tip.

  • Grant,

    Thanks for the update on the Mac Pro. I am an early 2008 (3,1) owner and as I stated earlier in the comments could not update the firmware. I am happy to see that you have indeed recreated the issue in house and acknowledged it. I am not having any issues with the drive so can not justify the down-time to ship back for an update, but would like to have the option to update at home as I’m sure you can understand.

    So my question to you: now that you have discovered the incompatibility issue with the updater on our machines, has a fix been identified and/or planned for a future update? Or.. are we stuck needing to send the drive in for updates indefinitely?

    • Hi Dale…never say never. We’re looking into solutions and workarounds…but do not have a timeframe for that right now. As you say, not experiencing any issues with your drive….and not meaning to be glib here…but the old adage “if it aint’ broke” kinda applies here then.

  • hybernate is primary of 360, but if you have 310 or 320 you are also missing 343 enhancements as well. cumlative i’m sure there is a lot more reason to update from something really old to 360 no?

  • UPDATE 4/1/11

    The firmware UPDATER TOOL itself has been determined to be incompatible with Mac Pro model ID MacPro1,1; MacPro 2,1; MacPro 3,1

    To determine your Model ID visit:


    You have the option of having us update the firmware on your drive OR choosing not to update the firmware. Please note that the primary update to this latest firmware revision corrected a hibernation issue for MacBook and MacBook Pro owners. Hibernation is not an Apple supported mode with Mac Pros and therefore the firmware update is not an absolute requirement for Mac Pro owners. Should you wish for us to update the firmware, please contact our Customer Service department at 800-275-4576

  • My comments did not survive moderation (Written when I was frustrated as others in this blog comments).

    This is how I get it done:
    1) Erase the drive and use security option to write 0s
    2) Install a fresh OSX
    3) Install a fresh Win7 Bootcamp option
    4) Upgrade the drive, The drive need to be in main bay not optibay.

    Tried with PC, 4 different types of Thinkpad Laptops – Win XP, all fails.

  • “There have been two SandForce-related issues with some of these drives, both of which can be corrected at this time.

    For those with hibernation issues, this firmware corrects those issues.

    For those with sleep issues there is a physical parameter change that OWC can do in-house to correct.

    Please call our Technical Support team at 1 (800) 275-4576 for assistance with either issue.”

    If I brought the drive after march 20th did OWC fix the SLEEP problem (physical prarmeter change) before shipping my mercury extreme out? I think the comments needs dates on them so we can get an idea of when the issues people reported has happened.

  • I also tried in vein to get this installed. I have a 2011 i7 15″ MBP with the OWC 120gb as the primary disk. I have the sleep problem – drive hangs if the machine tries to sleep – every time.

    I also wasted several hours installing BootCamp and Win7 only to have the same reboot problem as mentioned by several users above.

    All in all a really frustrating experience. I’m in Europe for the next couple months so getting a replacement drive will be a big pain.

    I realize this is not directly and OWC problem, but rather with their supplier – and they are trying hard to communicate with users and get it fixed. But what a fiasco. And why tell your users to update the firmware when it is the problematic? You have a defective product in the field and angry users, please get it fixed soon!

  • So, I tried this on Win 7, ran as Administrator, saw the drive, then selected the package and gave it the OK.

    It locks the machine up — hard. I left it on for about 20 minutes in case it was doing something in the background but nothing. It didn’t do any damage either, thankfully. (It’s all backed up anyway.)

    Win 7 is on a NTFS partition, machine’s a 12 core MacPro5,1. Connected to a motherboard SATA port (but not in a bay, in the extra DVD slot.)

  • Ok, i am officialy frustrated!
    I’ve spent the last 5 hours of my life trying to make this work…
    First, i installed the ssd on a z800 HP workstation.
    The firmware updater did not see the ssd at all!!!!
    After trying and trying several different things, i finally gave up and i installed the ssd to a second HP workstation (model: xw8400).
    The firmware updater saw the ssd there!
    I ran the updater everything went smoothly, pc rebooted and after the restart i opened the firmware updater, just to find out that i am still on firmware 343.
    I can’t even remember how many times i formatted the ssd,
    how many times i ran the updater and performed the procedure again and again…
    Finally i am giving up.
    Can you please provide us with a damn tool that works?
    Seriously i could do something useful instead of trying to upgrade a damn firmware for 5 hours…
    And maybe it’s not OWC’s fault, but i paid 3000$ to get these 2 SSDs i have, so please don’t find me demanding for expecting them to work properly and not freeze the damn Mac every time it wakes from sleep…
    Thank you.

  • I did many test yesterday night because of the sleep problems. I found a solution for now. In Energy Saving, UnCheck Put the hardDisk to Sleep when possible and also install PleaseSleep (take controls over the OS X Energy Saver and force a Menu Click Sleep). I have version 343 and could not udpate to 360 (Crashing while Downloading sectors). So far , no more sleep hang(beachball)!

    • It appears that I got a bum download.
      On advice from the vendor, I downloaded it again, and it installs OK now on 10.6.7

  • btw, just curious, does this firmware support trim, when OS X does officlaly enable it? or if user hack enables it now heh (which based on what i’m reading i’ll probalby wait since some are noticing performance loss instead of gain).

  • Add another Mac Pro user to the list of troubles. Mine is a 1.1. I have 4x OWC SSDs running in a striped RAID 0 in a DX4 housing off a dedicated RAID card. Had to basically disassemble the whole machine so I could remove my 4 Velociraptors from the main bays and plug the SSDs into them to run off the motherboard connectors instead of the card they usually run from. All to no avail as the update would not actually change anything. (Using Windows 7 BTW, formatted to MBR, running admin). Wasted probably about 6 hours if not more pulling everything apart and running it over and over, to then have to reassemble everything when it didn’t work and I gave up. On top of this was running a backup then having to load it all back onto the RAID once I gave up. Please keep us up to date with info! Cheers.

  • My experience is similar to Brian and Dale’s, except I’m trying to perform the update on a mid-2010 Core i7 MacBook Pro 6,2. My 240 GB Mercury Extreme Pro installed in the DVD bay.

    I also spent most of the weekend trying to get the firmware update to work but I admit complete and utter defeat despite scouring the posts here for suggestions. Admittedly, much of that time was spent getting Windows installed on a machine that doesn’t have an internal DVD drive.

    I tried many times to run the update under both XP and Win 7. Here are my results:

    – Win XP SP3: The updater would report progress through ‘Downloading 128 sectors’ and then I would get an ‘Update Failed’ message. No reboot, just a failure message.

    – Win 7: The updater would show ‘Downloading xxx sectors’ and soon would reboot the machine, but after reboot the firmware was still the original version.

  • I am having the same problem as Adam.
    My machine it’s a MacBook Pro 6,2 (mid 2010) i7.
    I run the updater but my Mercury Extreme Pro 480Gb never goes to the new firmware version.
    I live in Brazil and for me it is very complicated to send the SSD back to you in US.
    I am trying to update via BootCamp.
    What can I do?
    Please Help.

  • Hi Grant/Everyone, greetings from Australia,

    I have the wake from sleep issue on my 120GB OWC Mercury Extreme Pro SSD fitted to the optical bay on my MacPro (MacPro 4,1).
    I have not tried updating to the new firmware because a. I don’t have windows on my drive and b. I now understand that the firmware does not fix this issue.

    I purchased my SSD from you on the 10th of March, so it should have the updated parameter setting, is this correct?

    I have not tried resetting the PRAM as suggested in an earlier post as the drive is currently sitting in a box waiting to be shipped back to you, should I need to.

    I have sent a help request to your tech people and am waiting for a response, I just wanted to let you all know that I have the sleep issue on my SSD that was purchased after the 1/31/11.

    I don’t know if this is related but I have also noticed that when I boot up sometimes my bluetooth is active and other times it isn’t, I normally don’t have bluetooth switched on.

    When I originally fitted the SSD I used my Time Machine backup to format the drive, I think I am going to start from scratch next time and install from the original discs, although this is going to be a mega pain in the arse.

  • Failed to upgrade on my MacBook Pro late 2006.

    I have 120GB SSD and it has 343 firmware. Drive is partitioned with Boot Camp and WinXP installed on 33GB partition. Boot into WinXP, start firmware update utility, drive detects fine, lists 343 firmware. Select drive, open the 360 package. Package loads OK. Click download to drive. Nothing happens for a good 60-120 seconds.

    Then it starts giving progress reports
    Downloading 64 sectors

    stays on that for 15-25 minutes and then reports firmware upgrade failed.

  • I also have a 120gb OWC Mercury Extreme Pro SSD with firmware 320A13F0 currently on it. As several others have reported, I too am unable to update the firmware through bootcamp (Win7 ultimate 64bit) on my early 2008 Mac Pro (3,1). I follow directions exact by creating a fat32 partition, rebooting into bootcamp, opening the flasher as admin, it finds the drive, I chose the drive and the firmware and tell it to update. Then it goes through the process of counting up slowly but surely. It quickly flashes on the screen that it is complete then reboots. After reboot, loading the updater again to verify the version reveals it is still at 320 and not 360. Also, just to note I have the drive mounted in one of the main 4 bays and not to any type of external card.

    This is frustrating to say the least, but I am not experiencing issues that would dictate the need to send it in so I am going to wait for another solution. I don’t have another computer to flash it from. It is crazy that there are so many issues with trying to simply flash the firmware on these drives.

    OWC, please acknowledge that you are aware of the specific issues with flashing drives on Mac Pro’s, because I have not seen that acknowledgement yet. I have seen several others in the comments describing the exact issues I am having on a Mac Pro so this can’t be just a one off thing. I specifically request that you test flashing your drives on a Mac Pro (several models if possible) for the next update you release…I’m really hoping you get this figured out next go around, because having to ship a drive back just to get it updated crazy.

    Also, please contact me if you need any additional info to help correct these issues with Mac Pro’s on future releases.

    • We’re aware of the reports from some customers of the problems they’re having with running the firmware updater on some Mac Pro models, and we are currently in the process of investigating this. We’ll post our findings when we can duplicate the issue, isolate it, and confirm a resolution.

  • OWC Grant/Michael,

    This needs to be publicized on Firmware Update page, not buried in comments – “You may have read or seen references to MacBook Pro model identifiers 5,1 – 5,4. These are the models specifically affected by sleep related issues, NOT hibernation issues. If you purchased your SSD BEFORE 1/31/11 AND YOU OWN one of these Model ID machines, we need you to send your SSD in to us so we can apply the parameter update (for sleep issues) and at the same time we can update it to MP4 (to address any potential hibernation issue) if you have not already done so.”

  • Has anyone tested the SSD in the optibay and still have the same problem with sleep when they have a known working hard drive or known working ssd (like an intel x25) in the primary/HD bay?

    Pre and post of OWCs fix? thanks

  • There have been two SandForce-related issues with some of these drives, both of which can be corrected at this time.

    For those with hibernation issues, this firmware corrects those issues.

    For those with sleep issues there is a physical parameter change that OWC can do in-house to correct.

    Please call our Technical Support team at 1 (800) 275-4576 for assistance with either issue.

  • it seems no one with a mac pro is able to update the firmware in the mac pros internal SATA controler, besides myself i’ve now seen 2 others with mac pros also confirm they couldn’t update it whlie still in the mac pro. i hope this can be resolved in future updates so i don’t have to send it back every update.

  • After successfully updating to the 3.60 firmware, I’m still experiencing sleep issues with my MX480 in my MacPro1,1. I’ve confirmed that hibernate is off. I suspect that I might have the “incorrect settings”. Is there a way to confirm this before arranging to send it in to have the settings fixed? My MX480 was from order L2675930, which I received well before 1/31/2011.

  • Hi everybody,

    I’m writing to throw some light on the sleep issues we all have experienced when using an SSD.

    I own a Macbook Pro 13″ early 2011 with an OWC 120Gb SSD I bought last February (revision: 343A13F0) which, as OWC states, has the updated parameters for sleep.

    I have not updated the firmware to the 360 revision and I don’t plan to do it. I’ll explain you why later.

    Many of you are reporting this SSD related sleep issues so I’ll try to give you an answer/solution that works since I’ve experienced these too:

    1. “I set my Mac to sleep after n minutes but when the time passes my Mac never goes to sleep completely (symptom: sleep indicator light NOT blinking)”.

    Well, this one is easy, all MacBooks with an SSD as the main drive show the same behaviour even those with an Apple SSD, it’s normal and may be corrected in MAC OS X Lion.

    You can read this post on this matter: http://www.richardsnotes.org/archives/2011/03/24/macbook-pro-ssd-sleep-issue/

    Note: A friend’s Macbook which has an Apple SSD in it shows the same behaviour so that blog post is 100% right.

    2. “When my Mac wakes from sleep it gets frozen, hangs, shows the beach ball etc…and I need to restart or force a shut down.”

    You need to reset the PRAM and that will fix it (I had the same problem).
    You can learn how to reset the PRAM here: http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html

    Final note:

    OWC has published and updated firmware, the 360, to solve the hibernation issue. Let’s clarify what “hibernation” is:

    Apple developed 3 different behaviours for sleep:

    – hibernatemode = 0 (normal sleep)
    By default on supported desktops (iMac, Mac Pro, Mac Mini…)
    The system must wake from the contents of memory.
    The system will not back memory up to persistent storage.
    The system will lose context on power loss.
    This is, historically, plain old sleep.

    – hibernatemode = 3 (safe sleep -> hibernation in case of power loss)
    By default on supported portables (MacBooks).
    The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep.
    The system will wake from memory, unless a power loss forces it to restore from disk image.

    – hibernatemode = 25 (“pure” hibernation)
    Only settable via pmset.
    The system will store a copy of memory to persistent storage (the disk), and will remove power to memory.
    The system will restore from disk image.
    If you want “hibernation” – slower sleeps, slower wakes, and better battery life, you should use this setting.

    OWC is trying to solve the hibernation issue, that is, hibernatemode is set to 25 (not by default on any mac) OR it is set to 3 and the mac runs out of power/battery while sleeping (this is the typical scenario).

    Although I haven’t tested if the new firmware solves the hibernation issue (because I set hibernatemode to 0 and thus hibernation is disabled even if my MacBook runs out of battery while sleeping) I’d bet OWC has actually solved it.

    To those of you having issues, reset the PRAM and test again.

    Hope this helps some of you ;)

    Good luck!!

  • Well, after several failed attempts to upgrade the firmware for my MX480 and MXE120 on my MacPro1,1, I almost gave up. Then, I managed to install Windows 7 on my MacBook5,1 without a DVD drive (I have an OWC data doubler). After spending a day getting Windows 7 installed, the firmware worked without a hitch to upgrade both drives. Now both my SSD are running 3.60. I’ll need to do more testing to see if my sleep and hibernate problems are resolved.
