Hi, I recently bought a Western Digital CAViAR GP WD20EARS 2TB. The problem is I cant get it working, every time I plug it in it doesn't display in my BIOS and further more if I plug it in it disables my other 1TB Samsung drive, and then only my 160 GB drive shows. I have gotten it to boot once but then it gave me an "disk cannot be formatted" error.I tried to only plug in the 2TB and it still doesn't display. I have updated my BIOS, plug it in different SATA slots and set jumper setting but nothing. Is it a faulty drive or a PSU that not strong a enough? I have a g31m-s2l mobo.
