Getting "Disk not readable" message after installing and partitioning new HD.

I have a Power Mac G5 with two internal hard drives. I recently started having problems with the machine crashing and getting messages on restart that "the disk you inserted was not readable by this computer". Eventually, the second hard disk stopped showing up at all and would not show up when I tried Disk Utility, R-Studio or Disk Warrior.


After the hard drive stopped mounting the error messages stopped and I thought the problem was with the drive. I removed the drive and sent it off for data retrieval and bought a new Seagate Barracuda 1TB drive.


I installed the new drive and upon restarting the machine crashed again. I was able to bring it up and using Disk Utility partition the new drive but whenever I restart I still get the "The disk you inserted was not readable by this computer" screen with options to Ignore or Eject.


The partitions appear on my desktop as I named them but now I'm wondering if it's not a drive issue but maybe an issue with the connections to that drive bay. Should I replace the cables with the ones that came with the drive?


Any help would be greatly appreciated.

Thanks... have never even used that utility. Here's what I get... anything jump out about those kernel extensions?

Dod you install some Seagate Software?


Is that a "Green" drive?


Try a Safe Boot from the HD, (holding Shift key down at bootup), it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions.


Do you get the error with a Safe Boot?

Does that make sense?


Actually, it does, in another possible vein. Peek now in your /System/Library folder and look at the modification times for these two files:


Extensions.mkext

Extensions.kextcache


My guess is that they will have the about same mod time as when you restarted (as will the Extensions folder). At boot, if the mod time on the Extensions folder is later than the mod time on those files (which it would have been after you trashed the file), they are supposed to be rebuilt. Otherwise, they will be used to load kexts as needed by the system, which is how you get a (sometimes) damaged kext loaded. Usually it causes more catastrophic problems, but sometimes it may be a kext that is just incompatible for whatever reason, and you get strange but not catastrophic behavior.


More MacOS voodoo.
