Hello everyone,

A friend of mine bought a 3TB Seagate SATA drive off eBay about a week ago. He has been having trouble with it since. He said at first the disk showed up in disk management but after a while stopped showing up all together. It wont show up in the BIOS, device manager, etc. His brother took it to the IT faculty at school and they said that it was marked as a server/RAID drive but didnt know how to change this or reset it.

Should this effect whether the disk is seen by the BIOS/Disk Management?
Is there any way to fix this or is this disk shot?

He contacted the seller on eBay and has yet to hear back.
