I have a hard drive that I need to destroy the data on. What is the most
dependable way to do this? Can reformatting the drive as ext3 or ext4 or
some other filesystem effectively destroy the existing data?

Is there free software that can write zeroes or some form of nonsense to
every storage location?

shred (man shred) will do it.  "dd if=/dev/zero of=/dev/sda" would do
it.  Not that none of these guarantee that a disk will be unreadable.
Not even commercial programs.

No matter how many times you rewrite the media, someone with equipment
sophisticated enough may be able to read the data.  The only way to
ensure that a drive is unreadable is to physically destroy the platters.
Scraping off the magnetic coating into a fine dust is probably the
best...it would be possible, given enough time, to reconstruct a
shattered platter.


I haven´t done this task from Linux, but if you´ve got access to a windows
computer (or VM)  and you can install the drive into an external USB
enclosure, use this GPL program
