I purchased a new Seagate 1tb Barracuda 7200.12 hard drive 1 month ago and installed it successfully. I experienced no problems with it until yesterday when I turned off my PC. When I powered it up a few hours later, the drive didn't appear in Disk Management and wasn't even recognized by the BIOS.
Is there anything else I can check to determine whether the drive is dead? Jumper settings, power supply, etc? I'd like to be sure the drive is defective before I send it to Seagate for replacement.
