I just got a 2TB Western digital green drive. When i plug it into the PC my bios doesn't recognize it, but sometimes it does for some reason. Depends on the boot, then when i get it to show up in disk management it wont let me format, it says failed. I have updated to the latest bios and nvidia drivers. I have a xfx 790i ultra sli motherboard if that helps. Does anyone know why it wont work? I have googled this and it seems to be a common problem with large drives like this, and i dont think it is a bad harddrive since so many people are having the same issue. Thanks for any help.
