Hi, I've been having a problem with my CDRW recently. Today is the second time it happened - last time was a few days ago, and the only way I could solve it was to reboot (after an uptime of over 4 months), after which everything worked fine. My guess is that there's something going wrong with the SCSI emulation, but I'm not sure since I can't figure out the error messages. And in any case, I couldn't find any way to reset the SCSI bus if I am right. I'm enclosing below error messages I get when I try to write, blank or eject a CDRW. The lights on the drive don't go on - nothing seems to happen. And after a few seconds I get these. As I wrote, rebooting solves the problem, but that's obviously not the way :-(
