DoD Harddrive Secure Erase Wipe
DoD Harddrive Secure Erase Wipe
I have a project which I need to DoD harddrives for the company. I have large raid-scsi enclosure which I can use. I have access Quad/Octa Xeon P4 servers with 3 dual channel LVE/SE ultra scsi 160 cards. With these, I would be able to drive 4 x 14 scsi drive (IBM EXP300 / 3531-1RU) units. What are my options? I was thinking about doing following. 1. for i in 1 2 3 4 5 6 7; do time dd /dev/random of=/dev/sda bs=1048576; done Use the random bits into drive 7 times. I think with 14 x 36GB scsi in raid5 setup would take approximately 18 x 7pass = 5 days. This is pretty bad. 2. I could setup stripped version of gentoo with proper raid controller driver(here IBM ServeRaid 4Mx and run DBAN from boot drive. I've got a question, does anyone have working knowledge of DoD5200.28- STD & DoD5200.22-M? I need to know how it's supposed to work, then I could just write simple c program to erase drive instead of relying on other tools for speed. I need fastest solution available. Thanks. |

I see that "Eraser" does DoD wipes, and has open source: http://www.heidi.ie/eraser/ |

It might be quicker for you to do a quick format on all the drives and copy a large harmless file to the drives as many times (different folders) as required. Why not just copy files from a DVD film onto the drives - this will overwrite all sectors on the drives and only take you a few hours. You can then do another format to remove the material. |
