It may not erase all data if the device can do block relocation and you
don't have direct access to phisical blocks. But if data remains on
hidden or discarted blocks it is still hard to someone else recover it.

Hi all,

After reading a while about wiping [1] I think there's not a unique
way to do it. Finally I've chosen a simple double-step method:
First,
$ dd if=/dev/urandom of=<disk_to_delete>
and next
$ dd if=/deb/zero of=<disk_to_delete>
?Do you think is it safe enough? I mean ?is it enough against the
common recovery low-level data tools?
