I have a WD20EURS-73TLHY0 2TB drive that a pulled from a SpaceMonkey.com. I hated that service so I decided to cancel my subscription and use the bare drive instead.
The problem is that I can’t format the drive. It always gives an I/O error. I tried on Windows and on Ubuntu (see pictures below). On Windows I used diskpart and saw that the drive has a null DISKID, which seems weird. Now I’m thinking that it has some sort of special firmware made by SpaceMonkey, is that possible?
Did you try writing zeros to the hard drive before attempting to format it? It should clean the hard drive and allow you to format it unless there’s a firmware lock.
