[ale] Secure drive wipes on ext4 file system?

I have external USB drives that I need to do a secure wipe on regularly. I
have been using the 'shred' command but I just read that shred does not
really work will on journaling file systems.

The only other think I can think of is to do a manual 'dd' to the drive to
write over every single sector.

Thoughts?

Kind regards,
/Raj
