I take it this only works on ext3 boxes? Seems fairly filesystem specific, although I by no means am a filesystem expert. Matt Smollinger Application Engineer for Convergence Tech. AdvancedAV

It was suggested to send it to this list. The script reads /etc/fstab and automatically does a "dd if=/dev/zero..." on each ext3 partition. The script was created for Fedora Core, but should work on other distros/*nixes with just a little adaptation. Matt #!/usr/bin/perl # Script to zero out all free bits on disk prior to imaging disk with G4U open FSTAB, "/etc/fstab"; while (<FSTAB>) { chomp; if (/ext3/) { if (/\s+(\/[0-9a-zA-Z\/-_]*)\s/) { $fspath = $1 }; print "Zeroing out free space on $fspath\n"; unless ( substr($fspath, -1) =~ "\/" ) { $fspath .= "/" }; system "dd if=/dev/zero of=${fspath}0bits bs=20971520"; system "rm ${fspath}0bits"; } } This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
