I bought two Toshiba SD-W1101 DVD-RAM drives a few years ago but was never able to use them on my linux servers (only on my windows desktops) The main reason for this was that I never bothered to look for patches etc. to make them (or UDF) work. Though another person on this list made some comments about UDF a while back and I had a quick look but gave up. However, I had one of the drives in one of my Linux boxes as a CD/DVD reader (running 7.3) Last month I re-installed it to RedHat9 Then about a week later - for no apparent reason - I thought I might put a UDF formatted DVD-RAM disk in it and see if it worked. Wow - it behaves like a slow 2.6G HDD (about 1G per hour) So UDF is now there and I assume you could use it on any appropriate rewitable medium. -- -Cheers -Andrew MS ... if only he hadn't been hang gliding!
