It wants to read data to identify the kind of filesystem or device usage.
A blank CD delivers no data.

It cannot be mounted in the meaning of Linux mount. No data, no mount.

Now that's at least a different SCSI error. The drive dislikes some part
of the third WRITE command. But again the burn preparations and the first
two WRITE commands were accepted.

Was this a surely yet unused medium ? (Not the one which appeared to be
blank after the burn failed on the other drive ?)

Only 300 blocks were written. Among them block 16 which contains the
name of the ISO and its size.

Same manufacturer, different models.
The error code from the T400 laptop makes even less sense than the
other one. Why did it accept the first two WRITE commands ? They differ
from the third only by target block address and by payload data.

Well, if this was with the already touched CD, then re-try with a new one.
If it was already a new one, then i run out of ideas.

Try "Schreibmodus" TAO. Disable "Datenstromaufnahme".

Try "only create ISO" in Xfburn and then burn the resulting image file
by wodim:

  wodim -v dev=/dev/sr0 fs=8m -tao -eject padsize=300k image.iso


  wodim -v dev=/dev/sr0 fs=8m -sao -eject padsize=300k image.iso

Have a nice day :)
