HP usb 3.0 flash drive 128GB, tried multiple ports, no luck. Doesn't show up in My Computer/ This PC nor under Macrium's software, but it does under disk manager under Drive letter H:. To make things even stranger, the drive shows up under diskpart, but lists no partitions and shows 0 size and 0 available space. I have nothing of importance on the drive, how can I wipe it clean to factory so i can get some use out of it?
