I bought 2 drives, both the same, both from ncix.com, both 1 terabyte WDs. I've tried them in 2 computers with known working sata hard drives. I can't believe that I would've received 2 faulty Western Digital drives. All the settings are correct in the bios as far as I can tell (as I said other sata drives work with the same cables, ports).
I tried on a M3N78-VM Asus motherboard and a Abit AB9. I tried booting into vista on one just to see if I could see it in the disk manager, but of course it wasn't there.
Any help would be appreciated.
