CLICKY CLICK----> Negative Value Error Codes
Disconnect all devices from the computer then do the following:
Boot up from your Snow Leopard Install DVD while holding down the "c" key.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
Once this process has been completed restart your computer and repair permissions directly from Disk Utility.
If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.
Mac OS X (10.6.1)
Use Software Update or the OS 10.6.8 combo update to update your OS. Also, update everything SU has to offer for your computer. When done, repair permissions and restart your computer.
besides, is it likely that the exact same issue would arise with both drives?
More than likely if you transfered a corrupted OS from old to new drive. Did you click on the link I posted? Did you update your OS as previously suggested?
I am out of suggestions. If no one else chimes in here, take your MBP to your local AS or an AASP. Diagnostic testing is FREE!
The 10.6.1 listed in my first post is wrong, my mistake. I'm running 10.6.8
Please correct your system profile. Thank you. This will help in providing you w/correct troubleshooting suggestions.
If the problem is that the OS is indeed corrupted, how could I rectify that?
You never provided us w/the outcome of running DU directly from your system DVD. If you have a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius, use one of them.
Will request that the HOST move your post to the SL forum.
