zerofill - clear unused disk space and blank devices.
zerofill [
options] [
devices]
...
This command is a relative of nullfile. Like nullfile, it can be used to write
all unused disk space with '0', thereby making file systems that are stored on
virtual machines easier to pack. In addition, zerofill can fill unused disk
space with random data before zeroing, which can be useful to remove forensic
trace of deleted files. Finally, zerofile can be told to operate on and zero
(erase) complete disk devices.
