There would be be other ways, but you can use dd :

All zeros:
Code:
dd if=/dev/zero of=/dev/[yourdiskhere] & 

Random data:
Code:
dd if=/dev/random of=/dev/[yourdiskhere] & 

you can also check progress like this:
Code:
kill -SIGUSR1 [the pid]

You may also want to change the block size to speed things up. I have been using bs=4096 RTFM ;)

Regards,
Stonie.

PS: Make sure you read the man page.

Oh thats right... you could also use Dban.

Either way you will need to remove the disk from your NAS and mount on another box.

Since I need to do some scrubbing myself this afternoon... I did a bit more research, the tool that the DBan live CD uses is available as a stand alone application for Linux called NWipe works a treat. tidy ncurses interface.

Ok I realise I’m talking to myself... anyway here are the results of my research:

I did locate another option, scrub: http://linux.die.net/man/1/scrub

Also worth noting that if you want to clean a disk without removing it from your NAS you could use foonas em: http://foonas.org/index.php/Category:Foonas-em
Foonas-em includes busybox which includes dd so you could TFTP boot foonas-em into ram, then scrub the installed disk from there with dd as described above, this will save you disassembly in the case that you wish to sell the whole nas.
Note: You will need netcat enabled UBoot or a serial port.

In summary after trying out all these options I would recommend NWipe it’s the best all-round choice IMHO, it would be great to include it in foonas em in the future :)

Thanks ! Your not talking to yourself, I bookmarked the page and notice the updates to the first reply. I've stripped the unit down already and hooked it up to another PC. I've got DBan to hand and some other apps to wipe it. Thank you for the replies!
