My friend game me BARRACUDA ST31000528AS 7200.12 1TB Drive for temporary use. I had connected the drive in my system. The hard disk was first detected in the bios. After after a reboot it disappears. I had checked the drive it is spinning up, so that means that it is receiving the power enough. I checked certain settings in bios that was responsible for drive detection. All are fine. Not the drive is not detected at all.
