A Russian computer engineer was surprised when a customer brought a 500GB Samsung hard drive in for repair. Instead of the actual hard drive it contained 128Mb flash drive and a couple of metal nuts. But here is the clever bit. The drive cleverly downloads file in from the computer until it’s full and then starts dumping it until all it’s left with is the last part of the file. All other files on the drive stay intact and the file size of the now incomplete file is reported correctly.
