You said you dont care about the data so just reformat the drive and reinstall the OS... But you can use testdisk to try an recover the previous partition. http://www.cgsecurity.org/wiki/TestDisk

try a new power and data cables to rule them out and if its still not being seen by the bios then have the drive sent in for warranty exchange/repairs.
