You said: The results screen wouldn't be able to say anything much other than "Free space wiped. " That's the point, my results screen does not even say that. I was asleep during the first wipe. There was no indication that the wipe free space had completed. Every developer knows that it's a cardinal sin not to notify the user that a requested action has completed, especially when that action takes four hours and wears out the hard drive. That's why I thought the hacker had stopped it, so I wiped again when I could watch the whole process. The second wipe was two and a half hours shorter, which seemed suspiciously truncated. So I ran a third wipe which proved that four hours was standard. It seemed to me that the hacker was spooked by my first post to you and so shortened the second wipe. Even though I have not been able to send emails from my laptop's internet connection for 18 months, my email to CC was hacked. He read your second reply before I did (hackers have their grammar of gloating). My hacker is not imaginary, The Police informed me, some years ago, that malicious emails had been sent from my laptop.
