I downloaded their 192KB utility first. The basic test caused the drive to reinitialize, but still found no problems. The thorough test found no problems. I'm running the full Data Lifeguard test right now. It locked up the first time it tried to run because the drive reinitialized during the startup of the utility. Ok, now it has opened to the diagnostics portion. It's the same tests as I already ran. It just reinitialized too.
Ok, just hit "Quick test." As soon as it started, the drive clicked and reset itself. But for some reason, it finds no problems. I'm getting an RMA as soon as I can. Of course WD is closed Sundays, and will also be closed Monday. Grrr...
