DVD RAM drive and CentOS 4

[rbt at iag.net (Robert Tate)]

I just picked up a Sony DRU-820A, 2 layar, DVD+-R, +-RW, RAM drive. It seems 
to be ok in the normal modes, but I'm not sure what I need to due with the 
RAM usage. I have some DVD-RAM disks. I put one in on the off chance it would 
just work, but it said it wasn't formatted. What do I need to due to use the 
this in RAM mode. I didn't find anything that seemed to be aimed at this.

Thanks in advance for any pointers on where to look for info or what to do.
