So heres the deal, my new Dual 1.25 G4 jsut arrived today. I got it with an 80 GB drive. I also ordered another 80 GB drive form amazon, and it arrived a few days ago. So I booted it up, looked around, and shutdown. I didn't wanna spend time setting it up because I knew that raiding the two drives would destroy all data on them. So I Installed them, booted off the OS X CD< opened disk utility, dragged my two disks over to make a raid, and was that simple, then I just installed OS X and it flew, everything worked great. But I later decided, since I have so much stuff on my old G4, I'd be better off giving Carbon Copy Cloner a try at copying everything before I reinstall everything from scratch. So I went to reformat my RAID volume. This is when stuff started to get weird. I tried to erase the volume and it would seem to erase it, only it would do it really really fast. But when I looked at the drive, all its files were still there. When I clicked on raid in Disk Utility, it tells me there is a problem with my disk set. But when I try to delete the set, it just does nothing. The app just sits. How can I break up this disk set, so I can start a fresh one and try and get all my stuff over to my new computer? Right now I'm using my new one but I'm booted off my old one using FireWire Disk mode (or whatever its called)

Were you booted off a CD or external FireWire HD when you tried to bust up the RAID? If not, do that...

Try taking one of the drives out...boot off an external device or CD, install the OS on the remaining drive and later add back the drive you took out....

Ouch, software RAID 0 mishaps suck very much. Good luck.

Even with one of the drives disconnected, it still knows there's supposed to be a raid there and it still won't let me format the one drive thats still there. It appears that you have to delete the raid set before you can format a raid drive, and I can't do that, because it won't let me delete the set.
