erase free space error after defrag


New Member
On trying to erase free space on C drive, I get the message 'an unexpected software exception occurred at Oxc0000409 at location 0xc1001a214' and eraser quits. I ran a disk defragment on C before doing this, which I *now* see I shouldn't have done. Is there a way to run a free space erase on C now?
