My Seagate hard disk got bad sectors and wasn't usable any more. Seagate's SeaTools utility also indicates that. It was under warranty; so I returned that in Seagate SeaCare center and got a replacement drive within a few weeks. But even the replacement drive had the same problem of bad sectors and didn't even allow me to complete a Windows installation. So I visited the seagate service center one more time and got another replacement drive in a week's time. But to my surprise, that was faulty too and crashed during Windows installation. The SeaTools tests did confirm that both the replacement drives were indeed faulty.
Considering this I have following question for the community (and I hope I have chosen a right site out of stackexchange collection of sites):
I have read that these replacement drives are not brand new but only refurbished ones. (People at seacare center don't seem to have technical knowledge about it!) I wanted to know if that is really the case? And how can two replacement drives fail in a row?
More important question - do you think there might be anything wrong with my computer that's causing the disks to go bad so quickly? Whatever I know about computer hardware, this might not be the case. But I want to get opinions from experts out here before I decide to give up on my current disk and purchase a new one.
