I’ve got a 2TB WD disk ( WD20EARS ) which reports as a 1 TB capacity harddrive.
The disk has currently no partitions on it. So I tried the Western Digital LifeGuard Diagnostics tool for Windows, which also reports it to have 1 TB of capacity. Writing zeros didn’t help either.
Does anyone have any ideas how to fix the disk back to factory settings. With double the amount of sectors?
