I have an hard drive that still mechanically "works", but it can't be recognized by Windows. The disk starts up and it dies and it keeps cycling over and over and it is never recognized. I'm not trying to salvage the disk, but I want to recycle it by giving it to Best Buy recycle program and would like to play it safe and REALLY delete all the info by writing 0s to it.
How can I do so if Windows is not able to recognize it?
