Hi all,
I'm about to send my notebook away for repair, and I would like to make
sure that the data I've erased from the HD is not recoverable.
Is there a Linux tool for overwriting unused disk space (not existing
files) with garbage, in order to make the old data unreadable?
My filesystem is ext3.
Thanks in advance!cat /dev/urandom>/tmp/junk
(or even cat /dev/zero>/tmp/junk
When this stops due to running out of room,
rm /tmp/junk.
And the same on each of the other partitions.
