I have a stack of hard drives here, is there an app that can Zero out a drive, like Disk Utility, but one that will let me do multiple drives at once? I've got enough firewire and usb dongles to hook a ton up at once.

You may be able to do it in Terminal, just launch a new window for each disk.

diskutil secureErase with whatever parameters you want.

secureErase [freespace] level device
Erase, using a secure method, either a whole-disk (including
any and all partitions), or, only the free space (not in use
for files) on a currently-mounted volume. Erasing a whole-
disk will leave it useless until it is partitioned again.
Erasing freespace on a volume will leave it exactly as it was
from an end-user perspective, with the exception that it will
not be possible to recover deleted files or data using utility
software. If you need to erase all contents of a partition
but not its hosting whole-disk, use the zeroDisk or randomDisk
verbs. Ownership of the affected disk is required.

Level should be one of the following:

o 0 - Single-pass zero-fill erase.

o 1 - Single-pass random-fill erase.

o 2 - US DoD 7-pass secure erase.

o 3 - Gutmann algorithm 35-pass secure erase.

o 4 - US DoE algorithm 3-pass secure erase.

Ummm, Disk Utility lets you open multiple windows and thus reformat multiple drives at once, doesn't it?!

Yep. Cmd-n will open a new window in Disk Utility.

Hah. Bless Apple, so simple. Thanks guys.

Figures. And now I'm done.

I gave the "two Disk Utility windows" thing a try, and turns out it doesn't work. Even though it looks like you can get multiple format's going at once, it really just hangs the second one until the first one is finished. Oh well. I didn't like saving time anyway :-/

you could always try my Terminal suggestion.

I haaaaaaate the terminal.
