Shred destroys all data on a disk. The challenge is: If you have a magnetic disk and write zeroes all over the disk to destroy the data, there will still be a possibility left to read this data if you are willing to put in an enormous effort. shred first overwrites all data using random data, then zeroes the disk.

Shred destroys all data on a disk. The challenge is: If you have a magnetic disk and write zeroes all over the disk to destroy the data, there will still be a possibility left to read this data if you are willing to put in an enormous effort. shred first overwrites all data using random data, then zeroes the disk.

Example:

shred -n 1 -z -v /dev/sdx

(One pass to shred, one pass to zero)
