<DIV><FONT face=Arial size=2>AFAIK unless you overwrite the data several time
using specific software then its possible to get most things back. One of our

Deleted Files off a hard drive</FONT> </P><BR>
<P><FONT size=2>Everyone,</FONT> </P>
<P><FONT size=2>I recently had a discussion with a coworker about the
subject of retrieving deleted files off a hard drive. We got on the
subject because we are having an audit on those company-owned computers
systems that some staff may have at home for business use. He claims
that any file can be reclaimed, even if a defragmentation has been
run. I thought that once a disk has been defragmented, those files
were truly gone, if the anyone defragmented the disk, the audit would
basically be a waste of time. Is this true? The computer
security group here is, I'm sure, quite good, don't let any limitations be
considered in any advise returned to settle this score. </FONT></P>
<P><FONT size=2>If it is possible, does that also apply to a reformatted
disk? I would think that a reformatted disk would be the ultimate
cleanup, but that would have me wondering now if a defragment doesn't
work. Which would cause some serious concerns at this location as much
of the stuff that I work with is very sensitive and would make me wonder
about correct processes when buying a new machine and excessing the old
one.</FONT></P>
<P><FONT size=2>Thanks for your help in settling the discussion.</FONT>
