I have an external HDD connected via USB-3 that I can't get Diskpart to clean. It's a drive I robbed from my XP machine that was used as a backup. I just moved it from a USB-2 enclosure to a USB-3 enclosure. It has an "OEM Partition" that I can't delete. I was about to ask about it and ran across this thread. Is this a limitation of Diskpart on external drives?
