indicate otherwise. This is a regular backup, I do one of my working home firectories, then some other stuff in other sessions. The data for this burn is <300MB, and worked with another CD of the same brand.
Man page seems to say exactly what I expected, the kernel didn't reject the command because it was illegal or couldn't transfer it to the drive. That lets out a raft of things like having the drivers loaded in the wrong order and such.

It is obviously a problem inside your drive.
That's helpful, I was worried that I got a CD burning error in my keyboard or left speaker.
I suppose the chances of getting more information on what actually happened are small, an ecc error on a write is non-obvious to me, since I would expect that to be calculated in the drive and not visible to the CPU.
