Not sure whether Harddisk1\DR1 is the Toshiba. If the problem comes back, I'll check the registry for which Harddisk number the Toshiba is: http://support.microsoft.com/kb/159865
The USB drives were not in the system when the errors occurred. The errors are associated with my 465 GB drive, which is definitely the Toshiba since it is the only drive of that size I have ever used on the laptop.
Forgot to run perfmon /report. :thud: My apologies. I'll run it if problems persist.
Yes, the only diagnostics provided for Toshiba drives are typically supplied by the PC vendor, which in my case is Sony. The scan and repair did not remove the bad sectors. I'll provide a screenshot of the warning I am given when Windows is finished installing and I can run the Ubuntu disc and select the Try Ubuntu option (so it is not installed to the hard drive).
I am not sold on the HDD being the sole issue either, but right now, it is the only possible hardware that is currently dancing around yelling "Hey, look at me!" so I'm looking at it. I'd like to rule it out before I start worrying about hardware that I cannot test with simple remove and replace methods. Anything that involves taking the system completely apart is going to be left for Sony's technicians via my warranty. I've already ruled out the RAM as the issue. The hard drive and optical drive are the only two items left that I can physically get my hands on to test. I don't plan on testing the optical drive since I highly doubt it would cause this much trouble, but you understand what I mean.
