low level HD format pgm

[fbsd_user]

My hard drive got hard read errors today.
Need pgm to do low level format to mark bad tracks so they are not
used any more.
This type utility used to come with the hard drive but not any more.
Been to mfg web site, they do not have this kind of utility any
more.

Anybody know if there is some thing in the ports collection that
will do low level format?
Or maybe on the FBSD CD2  fixit disk?
