After checking our Archives then reading parts of the man pages for mkisofs and cdrecord, I proceeded to write a few CD-R's. The single session writes appeared to work, but the multi-session appeared to work only once (not sure if it was the 1st or the last) based on what Nautilus displays. The mkisofs stmts are like: mkisofs -R -o cdi1.raw /home/dirtree And the cdrecord are like: cdrecord -v [-multi] speed=4 dev=0,0 cdi1.raw [cdi2.raw...] If I used -multi on all but the last session, shouldn't each of the dirtrees show in the TOC? The cdrecord running msgs looked normal. Any thoughts? Single session writes are OK for large saves, but a waste of media for incremental saves.
