MnSCU Approved Data Scrubbing Software, Procedures and Disposal Vendors

Revised July 9, 2003

PC based hardware scrubbing procedure:

Use one of the following approved software utilities to scrub data:

1. Wipe Drive Professional (http://www.accessdata.com/)
2. Data Eraser (http://www.ontrack.com/dataeraser/)
3. IBM's 'scrub3.exe' (ftp://ftp.mnscu.edu/pub/scrubdiskutility/)

MacIntosh based hardware scrubbing procedure:

Use the following approved software utilities to scrub data:

Jiiva SuperScrubber (http://www.superscrubber.com). Either boot from the SuperScrubber CD or attach hard disk to another Mac. Wipe with the 'Military' configuration.

Or use Unix 'dd' command. See below.

Unix based hardware scrubbing procedure:

1. Mount drive in another Unix workstation or boot workstation from installation CD.

2. Determine disk mount point (/dev/hda1 in this example)

3. Use Unix utility 'dd' to write data to entire drive.
   
   For a single pass wipe use:
     dd if=/dev/zero of=/dev/hda1 bs=8192
   
   For a multipass wipe use:
     dd if=/dev/urandom of=/dev/hda1 bs=8192
     dd if=/dev/urandom of=/dev/hda1 bs=8192
   
   Followed by:
     dd if=/dev/zero of=/dev/hda1 bs=8192
   
   
4. Verify overwrite:
     dd if=/dev/hda1 count=100
   
   You should see only 'nulls' ? no data.
   
   Note: Some Unix OS's may use /dev/random instead of /dev/urandom.
