Maxtor I've had a 30GB Maxtor hard drive in this powermac. I've been able to install Mac OS 8.6 and it worked perfectly, but when I install Tiger, I get passed the first CD and it reboots to either: an apple logo, no spinning circle, then a black box over the apple; -or- the apple logo and spinning circle which doesn't go away; -or- the apple logo and spinning circle, and then a bunch of lines of text are displayed on the screen. So every one of my attempts to install Tiger results in a kernel panic, except the first, which I was able to install successfully with both discs, setup my account and got to my OS X desktop... then the computer shut down, I turned it on again, and the kernel panic message displayed over the apple logo. Western Digital I also have a 80GB Western Digital drive. When I try to install either OS 8.6 or Tiger, the installer always results in some variation of the "Please try installing again" message. Basically, it doesn't work. For what reason, again, I have no clue. edit: Disk Utility brings up that this drive, when attempted to be repaired: "Volume Bit Map needs minor repair". What I've done so far... - Formatted these drives with Mac OS Extended (Journaled) formats multiple times, trying both one partition and two. - Zapped PRAM. - Open firmware and reset-nvram, set-defaults, and reset-all. I doubt those last two did anything, but still did them nonetheless. This has been killing me for days. Any advice please?
