Question ID: 293401
My company has some surplus UNIX servers and before we dispose of them
we want to make sure all data is permanently removed from the hard
drives. I am looking for the names of software packages that will
over-write the data to Department of Defense Standards (DOD
5220.22-M).  I can find lots of programs that clean PCs, but none for
UNIX drives.

I am not looking for an evaluation of any of the products just a list
of 3 or more software titles so that we can do our own evaluation.
Thank you

Hi Mollydog!

At the IEEE Computer Society's website there is a sampling of free and
commercially available sanitization tools that can be used to erase
hard drives.

I reviewed the list (table 4) and found that ?DataScrubber? and
?Unishred Pro? work with Unix.

Data Scrubber

?The Data Scrubber Hard Drive Degaussing Software is a software-based
product that erases - to Department of Defense specifications - all
data written to 5 separate data blocks in the computer.?

Features: 

?The Data Scrubber is available in Windows, DOS and UNIX platforms
(non-IDE Drives) and runs under SunOS, Solaris 2.6, IRIX or H/UX.

The Data Scrubber is DIS/DoD certified to the following standards: DoD

UniShred Pro

?This is a commercial product sold by Los Altos Technologies that has
some interesting features and certainly some limitations. It operates
on the same principles as wipe and secure delete, i.e. overwriting
data numerous times, then removing the data. UniShred supports most of
the main flavors of Unix (Solaris, HP-UX, AIX, IRIX). UniShred
overwrites not only all addressable areas of the disk, but also
renders the grown defect areas of the disk secure as well. The other
utilities fail at this as they can only access areas that the disk can
access.?

?UniShred has been recognized by many US government agencies such as
the Dept of Navy, Dept of Defense, and Dept. of Energy as meeting
their stringent regulations for disk cleansing and sanitizing. The
product supports all the predefined overwrite patterns specified by
these agencies and also allows the user to specify their patterns.
There is a good reporting system that allows the user to create a
hard copy of the actions taken by UniShred for audit purposes.?

BCWipe for UNIX

The BCWipe software is intended to give you a confidence that your
deleted files cannot be recovered by an intruder. BCWipe repeatedly
overwrites special patterns to the files to be destroyed. BCWipe for
UNIX offers two wiping schemas:
US DoD 5200.28-STD standard 
default is 7 passes defined by standard 
user-defined number of passes 

BCWipe for UNIX brings following advantage:

- Delete files with wiping. BCWipe for UNIX offers military grade wiping schemes. 

- Files slacks wiping. File slack is the disk space from the end of a
file up to end of the last block/cluster used by that file.

- Wiping a whole hard drive. This function allows the wiping of entire
hard drives which is useful where the user sells or disposes of the
computer of hard disk or where the computer is re-assigned to another
user.

- Bootable BCWipe CD/floppy. Bootable BCWipe disk is an ideal solution
for wiping plenty of hard drives.
