There used to be a switch for the PC-DOS format comand, which would 
cause the format utility, after formatting a drive, to write a character 
specified by the user, to each byte on the drive, so that, for example, 
in using the command, a person could fill a HDD with the character '1', 
from start to finish.

Perhaps, if an equivalent does not exist in any of the flavours of 
Linux, a person could write such a script.

But I am sure that the CIA or the NSA or some other subversive 
government agency, could find a way of retrieving data, unless a person 
uses a blow torch to erase the data.
