Am I missing something? Couldn't you just bring up a command prompt and type "format e:" - or some other drive letter?
While I cannot guarantee this article does exactly what it claims it does (I haven't tried it, let alone heard about this way before) I can speak for the way format works now days.
Drives come pretty much preformatted now days as to its sectors and such. Format just basically wipes the file data/directory/folder content, not the data elsewhere on the drive. It's possible to recover the data with a little work, primarily on the "folders."
I would hope that this utility, DiskPart, issuing its "clean" command actually does more than clear the data partition info.
