I don't believe it is. This is the info on it: WD2001FASS
I've been able to try a couple of suggestions made here. I switched to a different SATA connection on the MB (no difference; same result of an incomplete Format) and I've checked for updated drivers for the NVIDEA nForce SATA controllers (2 showing under Device Mgr) and anything else by right clicking under the Device Manager.
I'm at a loss for what the problem is. I think I will try to format the drives on a different PC, though I have to say I'm going to have a hard time trusting them since I haven't figured out what this particular problem is....
Anyone want to hazard a guess as to the reliability of the drives if they only format successfully in a computer other than the one their destined to be installed in?
