delete == delete

[Bryan O'Neal]

If I intend to have the drive move to a different use I will use boot
and nuke with a few passes of one method or another, reformat and load
the new OS.

If I intend to let the disk out of my supervision (sale/salvage) and
remain intact (for reuse), then I use boot and nuke also, usually a few
passes of one type and a few of another and then I reformat as something
wacky fs like NXT, or what ever I can get my hands on at the time.

If I intend for the drive to thrown away then I will do the same thing
and then take out the platters and give a platter to all the people who
really like shinny things ;)

I have this luxury because I usually don't have more then a few drives
at a time and I usually have a computer that goes with them, and I
usually don't have a dead line of less then a few hours to having it
wiped securely (a dozen passes of some boot and nuke methods can take
all night to finish).

It's not that they don't play nice with journalled filesystems.
Journalled
filesystems will have a window where the data that you tried to destroy
will still be recoverable through the filesystem's journal under a
certain
window of time but I don't think that window is very long. They put
those
warnings about journalled filesystem in the man pages for those
utilities
for the paranoid but it is good information to know.
