My friend has a WD 1TB HDD placed in an external enclosure, he plugged the HDD into his Xbox360 and formatted it. Afterwards he wanted to format the HDD back to NTFS 1TB. The Hard Drive shows it's only 320GB and when you go into Disk Management there are no other partitions besides the 320GB one. After running Check Disk, Windows Surface Scan (by DTI) and Testdisk in linux the drive comes up completely clean. Can anyone help me get the disk back to 1TB.
