I'm erasing my 500GB HD right now, beginning yesterday morning. Out of 7 passes, its currently at it's 2nd pass, with an estimated 2+ days remaining. In retrospect, I consider the amount of time left too long and don't really need the 7 passes. I'm glad I didn't go the 35 pass erase. If I stop Disk Utility now, will my HD run into problems? I wouldn't mind stopping it, then restarting one more time with a 1-tme overwrite, if that would prevent any problems.... Advice?
