Hi all,
The subject is auto-descriptive ;)
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?

I have typically used rm -P against mount points and that has worked
well for me. In one situation, someone at a customer site tried to read
data from the erased directories using various commercial tools he had
access to and failed.
