Hiya, I recently bought a WD Black 1TB, along with a SATA3 PCIe card. It worked fine for a few days, then suddenly Windows wouldn't boot - hung on 'loading'. I yanked the new drive, Win loaded fine. I added it again (hot plug ability on SATA3 card), Device Manager immediately shows it. My Computer (explorer.exe) hangs, Disk Management doesn't even load. WD drive software also hangs with the drive plugged in. Sometimes, the drive appears in My Computer, however with no partition information (still hung). Tried with/without the SATA card, tried using mobo slots, tried moving boot drive around. Seems like the new drive has lost the partition table, or something similar. Any other ideas to try? Since I live in Australia (and a non-capital-city), my returns process is expensive.
