I decided I did not want any of these external drives anymore after a few bad experiences with them, so I was going to sell the ones I had that were still functional. Before doing so, I was going to use WD's software that writes zeros to the drives so none of my stuff would be retrievable by the next owner. First drive went fine, then after doing the second one (each one takes about two days to do) and assigning a drive letter to it, Windows suddenly said that the drive was needing to be formatted before I could use it. I clicked OK and the format took another two days. Now Windows is recognizing the drive, but Disk Management says 2048,00 GB NTFS Healthy (Primary Partition), then it says 746,49 GB Unallocated in a box next to it.
I have read various other threads about unallocated drives, but not sure I've ever seen one where it happens after writing zeros to the whole drive.
What does this mean, and what should I do? The drive was working fine with no unallocated space prior to writing zeros/reformatting it, did doing so somehow cause the drive to screw up? It is highly annoying this process taking over 4 days to complete alone, and even more so when it apparently was for nothing or perhaps even damaged my drive.
Attaching screenshot from Disk Management. Any suggestions are welcome.
PS: I really hate these My Book drives by now and I will never recommend them to anyone, I much rather prefer WD's passport USB drives which I have had no problems with so far and I own over 20 of those.
