edbp(1) - Linux man page

Name

edbp - Erase disk bit patterns

Synopsis

edbp [<passno> [<blocksize>] ]

Description

The edbp program produces an ''endless'' sequence of byte block containing a pattern to overwrite a disk. Typically you will pipe the output of edbp into a dd command to overwrite a disk.

Return Value

The program returns exit status 0 on success, any other exit status indicates an error.

Examples

for i in 7 6 5 4 3 2 1 0
do
  edbp $i | dd of=/dev/sda
done

overwrites a hard disk 8 times using different bytes. The final ''edbp 0'' produces 0x00 bytes, so any OS installation routine will detect /dev/sda as new (empty as shipped after production) disk. =head1 ENVIRONMENT
