From: Jim Wells ------------------------------------------------------ The FUD continues with regard to this topic. I work with drives every day in data recovery and forensics and I have never been able to recover any data after a one pass zero wipe. I have tried this myself on several occasions just to test it and be sure and with clients drives that accidently formatted them with Windows 7. If you still don't trust it then might I suggest trying it yourself. Many tools out there like recuva & testdisk even the trial version of R-Studio. The Electron Microscope would literally take a year at best and it did work in the mfm/rll days. Windows 7 full format also zero wipes the drive so be careful with that one.

According to modern researchers, just overwriting once with a single, specific character (i.e. "0") should be sufficient to "sanitize" the drive.
