Our software works for NTFS and FAT filesystems and in the new version you can
also
wipe the free space to get rid of data that is left on unallocated portions of
the disk.
It was tested against encase which is one of the most popular recovery tools.
(apparently has been used to recover data from disks that have been recovered
from
the WTC incident although we can not confirm that)
We could not recover any data in our lab tests. We tested 7 different recovery
tools,
but encase is the most popular and we dont want to advertise for the rest too :)
Our application has not only the DOD wiping standard, but also peter gutmanns
algorythm
with 38 random overwrites, which is the most secure wiping methode we know of.
shred is ok but not good enough to really securely clean data.

Subject: Re: [Full-disclosure] Secure Delete for Windows
An exe? No source??? Just "setup.exe"???? Are you crazy?
Or .. get GNU coreutils for windows :
http://gnuwin32.sourceforge.net/packages/coreutils.htm
and just use 'shred'.
(although 'man shred' specifically makes note about journaled
filesystems -- which NTFS is. I have not forensically analyzed the
effectiveness of this tool on a specific file -- only on a block device).
SysInternals also offers a freebie tool called 'sdelete'. Source for
that is also available :
http://www.sysinternals.com/Utilities/SDelete.html
(and in the discussion about 'how sdelete works' they reference the same
problem regarding journeled filesystems).
If the emminently wise gent from GroundZero wishes to comment on how his
perticular product addresses these issues, then that might be fodder for
the list (versus the ongoing flames).
