DBAN is used when you are going to lose control of the media (because you are
selling it or throwing it out) to prevent people from recovering your data.
It isn't needed to prevent you from accidentally running code looking at
data left behind after a compromise. A reinstall (including rewriting the
MBR and repartitioning) is good enough.

Also related to this is that hdparm will let you use the secure erase
feature of disk drives that support that feature.
