As the formatting procedure of an unencrypted hard drive does not provide a safe method how to prevent a third person from private data revelation, the following method ensures the data sectors are overwritten N times with random data to provide a guarantee, that nobody can reveal them…

This post deals with software called GNU shred.


$ shred -v /dev/sdX

Advanced Usage

shred -n N -vz /dev/sdX

where N is number of rewrites (default is 3) and X is the ID of the SATA disk (hdX in ATA/IDE case).
