Slooow CD burning via FW on 7600 |

My configuration: 7600 with Sonnet 466 Crescendo, OSX 10.1.5 Radeon 7000 PCI video Powerlogix RapidFire PCI USB/FW card LaCie 24x10x40 CD-RW connected via FW port on the RapidFire Card (TEAC W524E CD-RW mechanism) Everything is working quite nicely, except that CD burning to the LaCie drive under OSX is ridiculously slow (like HOURS - my last attempt I calculated a burn rate of about 8 kB/sec!) I've tried burning via the Finder and iTunes and have the same problem. Reading CDs from the same drive works fine. Booting to OS 9.1 and burning with Toast Lite works correctly. Any ideas?? Anyone else have this problem? Other than the burn problem, everything else on my 7600 works great under X. HP USB printer and a USB floppy drive connected to the RapidFire card work well. Jaz drive connected to internal SCSI works too. Heck of a job, Ryan... THANK YOU!! The more I use OS X, the more I like it. Especially Developer Tools - what a great environment for writing software!

Thanks again for the help. The $15 MacAlly FW card with TI chips did the trick - CD burning now working. The G4/700 seems to be playing nice too! |

LaCie tech support informed me that the bridge chip set on my CD-RW is an Oxford 911. The Rapidfire PCI card appears to have a Lucent FW chip (visual inspection of the card). Hmmm. Just ordered a MacAlly 3-port FW card from OWC, advertised as having TI chips. We'll see if that plays any nicer. At $15 it's a pretty cheap experiment. Also got upgrade-happy and ordered a Crescendo G4/700, hee hee. :) Hope it works! |

I just seen something very strange durionmg the early boot process of the system. I do not know if this causes the problem but I think that it will be a nice idea for research. Well in my system I have the RATOC card (Witch is working prefectly as a firewire card) and the orangelink card. Well When it detects the card the hexadecimal number displayed does not have the same length for both cards. I think that this is wring as these numbers should be used in order to access the card. Just to mension about this |

Thanks for the feedback. gchron, the problems you describe sound VERY similar to mine, so I guess I'll research the chipsets. I wonder what the technical details of the incompatibility are, and if it could be fixed at the driver level or something? |

What is the actually problem. egonzales21 is correct. I can explain you the problem as I had it too. Well I had an oxford911 chipset box with a CDRW installed and tried to burn a disk. With the orangelink FW/USB2 card the disk could not be written in any way. On th other hand I could read it with no problems. In order to figure the problem I replaced the CDRW with a hard disk. Well with this configuration I would read from the hard disk with no any problem, but when I had to write the system was actually hanged as I took ages to copy a single file that was greater that 2MBs. The small files did not had any problem. (If they were written one at a time - If I had to grag a folder with a lot of small files the system hanged). Of course these problem were noticable only in OSX in OS 9 the hardware were working fine. So I changed the FW/USB2 card with a RATOC one. The problem was solved. So and in your situation I think that the answer is that probably the card is the problem. |

Errr, I'll have to dig around a bit to find out what chip sets are involved (unless somebody around here knows offhand...) Tho other than the burn issue, the drive seems to play nicely (i.e. reads CDs just fine). I should also add that it doesn't look like the slow burns under OS X are any good either - I just tried to play some MP3s I put on a CD, but they appear to be corrupted. The original MP3s still on my HD play correctly. |

Two questions: What bridgechip does your external drive use and what firewire chip does the RapidFire card use? For me, I have two external firewire drives that use an Oxford 911 bridge. A lot of them use TI chips. Apparently in OS X, this bridge only plays well with certain types of firewire chips like the TI, Lucent, or Agere. I had an older OrangeMicro FW/USB card that had an Optiplex chip and this no longer worked in X. I replaced it with an Adaptec FW card using the TI chip and now everything OK. |
