Gentoo Linux: Secure and Permanent Hard Disk Erasure
Posted on September 12, 2012
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.
Usage
$ 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).
