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.
