My grandparent's computer had an issue with the account login. After fixing it many times, the OS (vista. you now feel my pain) finally quit, so now I am trying to do a reset to get rid of the corrupted files. It's an old pre-built micro-ATX computer, so it's difficult to get the hard drive back in, without spending a while trying to line everything back up and slot everything back in, and I have the drive out now, hooked up to a computer that is far superior in every way, so I would like to preform the reset on it instead of waiting for 3 hours for the drive to reset with it's rightful computer. So, I am looking for a software that would allow me to reset the drive. I have recommended to them that they get a new computer, and they are considering it, but they miss their steaming pile of vista, so they want me to reset as a last resort. I'm resetting it anyway. Please, help me with finding this software.
