Run the western digital test, http://support.wdc.com/product/download.asp?groupid=606&sid=3&lang=en
That isn't your drive, but i think its the same one for all drives and i'm to lazy to hunt yours down. BSOD can be caused by a bad drive, and about 30,000 other things.
Start by testing your drive though, that's quick and easy.
Thanks. With the weekend I had time to run this utility.
The quick test failed.
The extended Test failed.
I tried repairing sectors, but that operation failed with "handling Error" a an error code.
I have this data backed up elsewhere, so I guess I will just trash the drive. 1st HDD I have ever had fail on me.
