I ran the Acronis DriveCleanser (U.S. DoD Standard) and got the data destroyed complete message. To verify I checked the disk and I don't know what to look for. Sector 1 thru 10 had "00 00 00" but after that it looked like "3F C2 BA C5" and so on. So, how can I tell if my data on drive is destoyed...do I just assume if I ran the US DoD Standard that my data is wiped out? After running the (US DoD Standard) I decided run the disk thru one more clean. This time I used the (Fast) method. When I verified the disk every sector had "00 00 00 00" So, does the U.S. DoD standard not look like zeros or ones? What's the better method to destroying data...DriveCleanser or File Shredder? I have to return my old HD to Dell so I would really appreciate someone to help me feel confident about sending it. Thanks!
