Lost OSX Partition on my 9600 |

I was working on my 9600 over the weekend and found the need to reboot into 9.1. When I did so and the OS came up I got an error message that the drive (partition actually) was unreadable and did I want to format it. I said no and now I cannot see my OSX partition at all. The drive is a 60GB partitioned into 3 parts, 8GB for OSX, 8GB for OS9.1 and the rest for data. Even when trying to reboot with xpost it does not see the OSX partition so I cannot select that as an option. Anyone have an ideas as to how to fix this problem without losing the inforamtion that is already on my OSX parition and/or reinstalling OSX? PM9600; XLR8 G4/450; ATI Radeon Video card (primary); Stock apple video card (secondary); Sonnet USB/Firewire combo card; Sonnet ATA100 IDE card; OSX 10.1 / OS 9.1 Thanks. Scott |

Thanks everyone for your input. It turns out the solution was to let the machine sit in the corner and think about what it had done wrong. (kind of like putting your child in timeout) When I got home yesterday to try some of the suggestions here I booted the machine and everything works perfectly. I am still going run checks on the drive and I may invest in a copy of disk warrior as well. Thanks again. Scott |

I don't think you'll need to use the trick of unplugging the drive and then plugging it in while the computer is running. That is sometimes necessary where a drive is so messed up that it prevents the computer from starting up. But that does not seem to be your problem. DiskWarrior would certainly be a good option--it is an excellent program. You could also try simply using Disk First Aid, though this may or may not be the kind of problem it can fix. Another option would be to pretend to install Mac OS X elsewhere (i.e. use XPostFacto to set up the install), but when the Mac OS X Installer appears, use the menu command that allows you to invoke the Disk Utility. That may allow you to perform repairs from there. (Alternatively, you can boot into single-user mode from the Install Disk, and then run fsck_hfs manually. But if you don't have any idea what I'm talking about, then one of the other options would probably be better). |

I had a similar problem with my 8500 and used the OS 9 disk utility and just reloaded the driver for the disk, but I was running 3 seperate 9 gig scsi drives and lost a drive not just a partition but had good luck after reloading the driver and rebooting. |

I've had this problem before. I had to open the machine and disconnect the power to the drive, I had another drive to startup from, reboot from the secondary startup drive, launch Disk Warrior, and then plug in the power to the drive while the machine is running. This is in OS9, of course. Sounds risky but it isn't really. once the drive attempts to mount disk warrior or whatever disk utility you have should see it and be able to repair it. Disk Warrior is far more successful though than Norton Utilities. You might also get lucky by booting with your utility disk and being able to do your repairs that way, provided that the disk that is giving you trouble mounts.

This actually happened on my 9500 last weekend as well. I thought it was a fluke done by something stupid in Fink or while I was mucking around in single-user mode. It's running 10.2.3 and 9.1 on (3) 120 GB Samsung SpinPoint ATA drives connected to a SIIG ATA/133 card along with 784 MB of RAM, Matrox video card, OWC FW, SIIG USB, and 2 RealTek NICs. There's a 300 MHz ZIF on an XLR8 carrier card. |
