anyone remember the file format, filesystem, of that stuff under windows, from roxio/adaptec, that lets you use a cdrw disk as a big slow floppy?
what support is there for it in linux and how? Can it do rieser? ext2/3? iso9660? rockridge/joliet?
thanks

~ UDF is what you want. afaik the only cd/cdrw/dvd supported formats are UDF and iso9660. Most DVDs use UDF.

Yes, UDF is probably what you want to use for any RW disc based media. Though, that's not exclusive. I have and use a DVD-RAM drive for long-term archiving and I use ext3 on it. As for other RW media, AFAIK, you can use other file systems on them. However, other file systems are not optimized for use with discs like UDF is. On the other hand, the DVD-RAM standard mandates that the drives manage bad sectors in the same way that a hard drive does -- automatically marking them bad and allocating the data to a new location.
Whatever you decide on, the entry in your /etc/fstab should be 'auto'. Use mkudffs to format the RW media. The kernel must also be aware that your drive can RW/RAM (most are compatible). You MUST not have ide-scsi enabled and you must be using the 2.6 kernel series. Do not install Kernel 2.6.8 or 2.6.8.1 as cd writing has been borked. 2.6.8.2 will correct this.
Also, it's worth mention that your "slow floppy" reference is rather humorous: at 1x DVD write speed, 1.39 MB of data are written to the disk every /second/ -- that's the entire size of a floppy. Maybe you were thinking of another media called floppy?
