I am trying to do multisession cd-writing. My system is a laptop with a Toshiba DVD/CDRW combo drive, running RH9. I previously was able to use gtoaster for trouble-free multi-session cd writes, but suddenly I cannot! The first write session is fine, but various errors occur on subsequent sessions.
I don't know when the break occurred: after I upgraded from RH8 to RH9, or after I tried using a USB2 DVD+RW (which worked for reading, but not quite for writing in Linux).
Anyway, I tried command line mkisofs and cdrecord to see if it would work instead of gtoaster. On a blank CDRW:
#mkisofs -r -J -f /home/jjstickel/temp/to_burn_symb/ | cdrecord -v -eject -multi speed=4 -
writes and mounts an initial session OK. To write some more, I try:
#cdrecord -v -msinfo ... xx,yy #mkisofs -r -J -f -C xx,yy -M /dev/scd0 /home/jjstickel/temp/to_burn_symb/ | cdrecord -v -eject -multi speed=4 -
seems to write OK; at least the output progress looks good and there are no errors. However, upon remount I can only see what written in the first session (yes, I put something different in the target directory)! Any help out there?

One thing I found with my LG-8080-B CD-Writer was that I had to literally eject the cdrom in order to make it recognize that the data had changed. (mount -o remount doesn't work, and umount && mount doesn't work, only eject && mount). That could explain why my Windows CD burner software always used to physically eject the CD then suck it back in, even without me asking.
I thought I had this covered by using the eject option with cdrecord, but I must have been shoving it back in too quickly, or KDE's automount was being wacky. Anyway, I swear it wasn't working when I made the post, but this morning I put the cd back in and I can see everything after all! Well anyway, I know how to do command line cd-writing now.
