Have been running cdrdao for years to created audio CDs, never had a problem until yesterday.
Using cdrdao 1.2.3 on Ubuntu 12.04 LTS.
Inserted the disk into the writer (/dev/sr1). Here is the command and the resulting console output:
Command is my usual syntax. I use "generic-mmc-raw" in order to get CD-text, and "--overburn" in case the audio files are slighly larger than the rated disk capacity. Neither of these applies here.
$ sudo cdrdao simulate --eject --device /dev/sr1 --driver generic-mmc-raw --overburn toc.txt

Simulation finished successfully.
The result is a disk that is now unreadable on any CD player that I have. Trying to run the same command, on the same disc, with "write" instead of simulate now gives repeated messages
Trying to run the same command, on a fresh disc, with "write" instead of "simulate", gives the same result as above, i.e., an unplayable disc.

Is this a sudden hardware failure? The disc writer is an LG External Super Multi DVD Rewriter, November 2011, connected to a USB port. Note that it is still able to read and play other CD audio discs. I also have, until now, written many DVDs on this unit, one as recently as last week.
Output from "sudo lshw" :
Note the last line reports "nodisc" even though there is in fact a disc in the unit.

Any help would be much appreciated !
