That looks normal so at the moment I do not think it is a module problem. Are you sure the disk you are trying to mount is a valid data disc?

With the questionable CD inserted post the output of the command (as root just to be sure):
file -s /dev/sr0

Could be a hardware problem...

The hardware problems in cd players are all around sensitivity. A good cdr that one dodgy drive may see as all zeroes another dodgy drive will see as all ones. That's the issue: seeing ones and zeroes where they were put.

Some drives read cdrs poorly, but this is rarely a problem unless one drive is very old. Anything over 40x read is usually free of this issue.

Also try setting the cd reading speed with eject command. Place the cd/dvd in drive. Then run:

Code:
eject -x 2 /dev/sr0
Replace sr0 with your cd/dvd block device file.

Report what happens.

to all...

device is now *working* Amazing. The only change I have made
was to change ~/.local/share/Trash/metadata from size=1.8exabytes
to size=0, this fixed "trash full when empty"

Not sure if to mark this thread "solved", or look for a Serendipity
option (LOL)

Thanks to all for trying.

It's not absolutely needed.

By the way I didn't understand what fixed your problem?
