Automated Partition Erasure tool or script

There are several machines that my IT department routinely has to wipe and return to our supplier (Dell). I know about the programs like Boot and Nuke, but those take far too long to be of practical use. Is there some program or image available or that anyone knows of that can wipe the partition of the drive without doing a full DoD wipe of the disk, that is automated and will run on bootup?

Put another way, is there script or program that i can burn to a CD, boot from and have it automatically erase the partition without spending 3+ hours doing a DoD wipe.

You can certainly boot from an install disk and run the clean command from diskpart. That would take less than a minute and a few keystrokes.

I'd guess someone could rig up a script to do it automatically.

"Clean" isn't DOD level, but it wipes the entire drive well enough for non-forensic purposes.

Thanks for the response. I should have included this in the initial post, my apologies to all for omitting it. I need something that requires no input or interactivity as the program/script is going to be burned and sent to end users to wipe their old machines when they receive a new one. None of the folks are particularly tech savvy and so it basically has to be something that can just run automatically on boot from a CD and clean the drive
