10.3: Use the bulk CD eraser to mass-wipe CD-RW discs UNIX
The new drutil utility has some nice features (see the man page). If you run
drutil bulkerase quick
in a Terminal, it will start the Bulk RW Eraser. This app opens the CD tray and asks for a disk. When you insert one, it erases it, opens the tray again, and asks for another one, ad nauseam:

~ % drutil bulkerase quick
Bulk RW Eraser

Please insert erasable media in TOSHIBA DVD-ROM SD-R1312.
Erase completed.                                                               

Please insert erasable media in TOSHIBA DVD-ROM SD-R1312.
Erasing... [**************************************

Just push control-C when you run out of disks. Very handy when you have a big stack of them to wipe. You can also do drutil bulkerase full if you're feeling paranoid.

Interesting tip--

Any way to choose my external Firewire CD/RW which is much faster than the one built in to my Ti-Book?

Yes, just type "man drutil" in the terminal and look at the DRIVE SELECTION CRITERIA section.

As the man drutil states:

drutil tray close -drive 1
Closes the tray of the first burning device seen, if possible.
drutil info -drive external
Lists drive specific information for all externally
connected burning devices.
drutil status -drive firewire
Lists media specific information for media present in
attached firewire burning devices.
drutil tray open -drive VENDOR
Opens the tray of all burning devices whose vendor id is
VENDOR, if possible.
drutil getconfig supported -drive 'CD-RW CDW827ES'
Lists supported features and profiles for attached devices
whose product id is 'CD-RW CDW827ES'.

So you can control any drive connected to the Mac.

Booyah!!! This is just what I needed. Toast is fine, but having to keep hitting those buttons really slows things own. Thanks again.

Aha! CD Tray opening is back in 10.3! This feature was in 10.1 then removed in 10.2 i believe...


drutil tray open
drutil tray close

I tried to use my Imac to erase a DVD-RW and it seemed to work, but back at the Powerbook, it does not see it as a new disk, and I can not erase it.
