I have run Drive Wipe twice on the same drive and there is one file that remains. I find it using Recuva. I also tried bleachbit with same result. This one file seems to defile all efforts to wipe it. It is named Outlook Express emails.zip with no last modified date shown and a size of 45,881Kb. I haven't used Outlook Express in ages, probably since Windows XP.
I highlighted it and checked Secure Overwrite Checked and got this message attached.
Anyone with any ideas?
