I am making backups to a DVD+RW using growisofs (latest: 5.17.4.8.6) on a NEC-1300A (1.05) (on Linux). Usually it runs without problems for a while but sometimes it doesn't.
After this I can't even mount the dvd unless I reboot or open the dvd manually. (It doesn't respond to cdrecord dev=0,0,0 -eject).
Can anyone tell me what the problem is and how to solve this?
Robin.
