How recoverable do you want the system to be? There are few quick attacks you can do if you don't care if the system can be recovered. You can wipe the partition table, you can wipe /boot, you can scribble over random parts. I've had to do quick wipes of different systems at the end of disaster recovery tests. Our security people were satisfied with a quick init of the disk. Sure, give the disk to somebody who knows what they're doing, and they'll get the data back, but if the system will end up with somebody somewhat trustworthy, it's good enough. Simply deleting files will make them recoverable with a simple undelete. You may want to copy random garbage to the drive after deleting files to get them overwritten. There are DOS applications that will write erasure patterns all over the drive. You could boot into something like that - heck, you've got access to grub, so boot into a standalone erase program, and poof, data gone. Test it on your personal production system first :-) -- Ed Wilts, Mounds View, MN, USA mailto:ewilts@xxxxxxxxxx Member #1, Red Hat Community Ambassador Program -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
