You mean your hard disk is dying and you want to overwrite it with NULs?
As you most probably will throw it away anyway, why not
simply use a hammer to destroy your sensitive data?
And maybe using a huge magnet before or after that ... ;-)
Otherwise, the ddrescue's are the right tools (as Padraig already mentioned).
dd_rescue: http://www.garloff.de/kurt/linux/ddrescue/ or
GNU ddrescue: http://www.gnu.org/software/ddrescue/ddrescue.html
Have a nice day,
