Corrupt Boot Drive

[Androzs]

I have an 8 core Mac Pro running 10.6.6 with PT9HD. With two different HDDs my main boot drive has come up as corrupt when I verify it in disk utility. I decided to verify it because PT was running particularly slow. I can repair it with the install disk using disk utilities and it says that it was repaired and appears to be ok, but a few days later if I check it, it will show up as corrupt again. I Have four HDDs in the computer, one is the boot drive with os and software, one for sample libraries, one for recording sessions, and another for mass storage. When this first happened I replaced the samsung boot drive with a new WD black caviar and a clean install of all software. Now, about a week later it is corrupt. What gives? Both drives can't be bad right?

Yeah.... Seems a bit unlikely.

I had a similar issue which was caused by a slightly loose HD connector on my G5 a couple of years ago... The cable which plugged into the drives had become faulty and was working intermittently...

Perhaps try swapping the position of the drives in the MacPro to see if there's an issue with the HD connector?

[Androzs]

Yeah so I forgot to mention that I did switch the position of the boot drive from the first bay to the fourth bay and the issue still pops up.

Buy Disk Warrior and use it to check/repair all of your drives.
It can find and repair more problems than Disk Utility. Also always have
an OSX system partition on more than one drive so you can repair your
main system while booted from another.

Do you have any external drives plugged in? You need to check
cabling and run Disk Warrior on the external drives too.
I've occasionally had problems with a firewire external drive
causing problems on the boot drive, especially during startup.

I've had this issue for 2 years or more... On totally different computers. With totally different drives. Diff everything. Drives me nuts.

I've never come up with solution. Except to run Diskwarrior, Drive Genius and etc once a week. Unless the 24 drives I've bought, 3 different Macs, and 20 gig of RAM I bought over the last 4 years is all bad, its just something that happens.

Its Worse after a kernel panic. After every kernel panic, run DW and Drive Genius or one of those guys.

And if you'll notice, its always the directory that's whacked. Its always one or two files less than its supposed to be. very frustrating.
