Everytme I attamept to wipe one of my slave drives with DOD Wipe my system freezes with message saying "1 of 2 wiping partitian, less than 1 minute remaining". I have WIN 7 and a very robust system. I have made three attemps, fixes attempeted applied updates, rebooted system prior and post operaion. Nothing seems to work. I have been able to use the Russian wipe option without any problem. Please help.
