Hi, I use mkisofs and cdrecord to create multisession CDs with my weekly backups. I have a CDR with already 2 sessions on it. I get the offset for the new session: $ cdrecord -msinfo dev=4,0 145740,157642 I make the image (foo.raw) from all inside /BACK to write it on the multisession CDR in dev=4,0: $ mkisofs -R -L -T -C 145740,157642 -M 4,0 -o foo.raw /BACK Now I see some messages of files being ignored (because of ~): Ignoring file diff11~ Ignoring file diff1~ Ignoring file diff0~ Ignoring file diff10~ Ignoring file diff12~ Ignoring file diff14~ Ignoring file diff13~ Ignoring file diff15~ Ignoring file diff16~ and so on... But then I get this message: **BAD RRVERSIONmkisofs: Nicht genügend Hauptspeicher verfügbar. Not enough memory And the program quits. It can't be the memory though. top shows: Mem: 193104K av, 61720K used, 131384K free, 50864K shrd, 5676K buff Swap: 120452K av 0K used, 120452K free 22420K cached There is also more than enough free space on the CDR and on the harddisk. I can't make anything of that 'BAD RRVERSIONmkisofs'. I already used this same version together with cdrecord for all my CDRs and never had any probs. Any idea? wobo -- GPG-Fingerprint: FE5A 0891 7027 8D1B 4E3F 73C1 AD9B D732 A698 82EE For Public Key mailto [EMAIL PROTECTED] with Subject: GPG-Request ------------------------------------------------------------------- ISDN4LINUX-FAQ -- Deutsch: http://www.wolf-b.de/i4l/i4lfaq-de.html
