I just bought the WD Caviar Green 3 terabyte hard drive I had to get the sata and what is it, p7 cables to hook it up. I got it hooked up and it ended up as a disk 0 and only 743.52G altogether. I called WD tech support and they had me format it then told me to contact the company that my motherboard was from. That is an Asus, I have a P5N-E SLI and I called them up and flashed my BIOS to try and get this damn thing to work and it still will not show that it is a 3 terabyte hard drive and I have run out of people to call except for windows... (I am running Vista). So just looking to see if I have any other options, WD didn't want to be at fault so they blamed my Motherboard and ASUS didn't have anything to do after they updated my Motherboard so BAHHH! Like a three day thing over here!!
