If recovery after one pass of rewriting a disk is a credible threat you should be physically destroying the disks. Writing over the disk multiple times is not going to reach some sectors (bad ones or spares) and for most people the threat of using an electron microscope to try to overwritten data is not a credible threat. So there isn't a lot of point of doming anything more than writing zeros over the disk, after the fact. Using block level encryption in the first place is a relatively cheap way to make recovery harder as well as protect against some other things. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
