How To Wipe Destroy Your Hard Disk Data Using Shred And DD Commands In Linux

You’ll likely be surprised to know that when you delete a file, the file contents aren’t actually deleted from the hard disk immediately.
Shred is a program that will overwrite your files in a way that makes them very difficult to recover by a third party.
the shred command is an important tool if your work involves dealing with – especially deleting – sensitive data.

The commands used in this video :
# shred – v /dev/sdx
# dd if=/dev/urandom of=/dev/sdx status=progress
# for i in {1..3}; do dd if=/dev/urandom of=/dev/sdx status=progress;done
# dd if=/dev/zero of=/dev/sdx status=progress
