content: I got 2-3 uses out of it. Intention when I bought this was simply to use for wiping drives. It worked fine on the first couple of drives (SATA). Now when I plug the USB cable in only the blue light appears. Depending on if I have an IDE or SATA drive attached, the white light for either of those blinks very briefly and the drive does not appear. I've tried this on 4 different computers running Windows 7, Windows XP and booting from a DOS CD. This is a really bad product.
