I have an external HD which used to be my TimeMachine drive. I got a different drive for that, so I want the original drive back as an external on my Windows box, but it has this random 200 MB partition labeled as EFI System Partition. How do I get rid of this?

  1. On the command prompt type diskpart and answer to any possible UAC prompt.
  2. On the new diskpart prompt, type list disk. Note the Disk ### column.
  3. Type, select disk xxx (with xxx being the disk you wish to delete. Usually the disk with partition 0 with a size of 200 MB) NOTE: The disk may not show the 200MB partition in the disk list in Diskpart even if it exists.
  4. Finish by typing, clean.
  5. Type exit to exit diskpart

Use DBAN to nuke all partitions on the drive (version 2 supports USB) and then create a new partition using Windows Disk Management.

If necessary, backup important data, as everything will be deleted.
