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.

the sysyinternals one might be more suitable, if you format the disk first
it should then be able to wipe the free space.

The problem with some of these utilities is that they might not work
properly on SCSI drives or with certain SCSI cards. Unless the makers
of the utility have properly tested and unequivocally certify their
utilities to work with SCSI drives I wouldn't chance it.
