How to delete your private data from Linux machine?
By pm - December 18, 2007
Due to certain reasons, if you would like to delete your private data in your Linux machine,
You should try:
dd if=/dev/urandom of=/dev/sda
This command will overwrite the data stored on the /dev/sda partition with random junk, however, there is a disadvantage with using the dd command and that is the speed that it takes to overwriting the data.
shred -v -n 1 /dev/sda
This will overwrite the data on the /dev/sda partition with random junk and at a much faster speed.
Again, there are certain security tools that may recover your deleted data somehow.
