[CentOS] wiping of unused space on ext3

  I was asked if it is possible to zero unused space in ext3 partition?

  Users write to the server via Samba and are far from computer geeks so
teaching them to use some safedelete utility is quite impossible.

  Is there some way or utility to wipe out all the data from unused space?
