The drive refuses to read data from the medium.

This is expectable if the medium is really an audio CD. Other than CD-ROM,
a CD-DA medium contains sectors of 2352 bytes each rather than the 2048
bytes sectors which SCSI command READ(10) would able to read.
Your reader program needs to use command READ CD or READ CD MSF.
mount(8) or dd(1) won't do this. (Also mount(8) would find no filesystem.)

Program "mplayer" comes to my mind as potential reader.
But i am sure the list members can tell more programs which play music
from CD-DA media.


Have a nice day :)

Thomas
