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. Bob Tate
