Need to be able to wipe flash drives, SD cards, etc. Family and friends need a drive/card and I've got one to spare, or something like that, but I don't want them being able to get any of my stuff. Also just for when the drive is too small/too old/slow and glitching a bit and it's time to recycle it. Seems like a place identity theft would occur. REALLY not expecting anything from this, because all I've gotten in response is how it's all proprietary/really difficult(not exactly sure how much I trust the scale of difficulty described from those people, given that there are multiple apps for Windows Phone that basically do the same thing in order to get rid of the mysterious "Other" data), but it can't hurt to ask
