The bin files are for converting drives to work on the xbox 360. The undo files revert the drive back to an original state, western digital 250gb,320gb,500gb,ect. If you can't find the right undo file i suggest that you to keep using the drive in the console or format it in a computer and use it for storage on a computer. You will only be able to use 320gb or 250gb of the drive depending on when you flashed the drive.
i know on the latest version of hdd hacker they have .bins for up to 1 tb but i can't figure out how to make or download a undo.bin for a 500 gb .bin for a 640 gb hard drive?
