UDF was designed for write once and RW situations, initially for Magneto-Optical drives. Later, sequential write once ability for CD-R was added to the existing random write once ability. The focus of UDF design was interchangeability. There is nothing in UDF that would have better performance characteristics over ext2 on DVD-RAM. You wouldn' be able to use ext2 on -R media, but that's not the issue. Further, the Linux UDF fs is buggy. -- Rob signature.asc Description: Digital signature

DVD-RAM questions
I have a couple of questions about DVD-RAM on Debian Sarge, kernel 2.4.27-3-686 If I format DVD-RAMs with ext2 most things work fine but there are two minor problems: When I shut down the system without manually umounting the DVD-RAM it does not get cleanly umounted like a hd or somesuch. When I'm formating a medium the system gets real slow and sometimes it does not react on user input any more for some time. Following some discussions on debian lists I got the impression that udf would be a 'better' filesystem for DVD-RAM. Is this true and why? I wanted to try and I did mkudffs --media-type=dvdram /dev/scd6 which did (?) it's job in a few seconds (while mkfs.ext2 takes a while) and then I could mount -tudf /dev/$DVDRAM_DEVICE /DVD-RAM muz:~# mount [snip] /dev/scd6 on /DVD-RAM type udf (rw) but I can't write files on the device: muz:~# > /DVD-RAM/new_file -bash: /DVD-RAM/new_file: Read-only file system What did I do wrong?
