Extracting tracks as WAV from a worn-out CD

[Razmig K]

Hello,

I could successfully extract the last track, no. 7, on a pretty worn-out 
audio CD issuing the command:
% cdda2wav -D 0,0,0 -t 7
(0,0,0 being the SCSI device corresponding to the cdda2wav -scanbus output)
while I have failed doing so earlier via:
% cdda2wav -D /dev/acd0 -t 7
since it got stuck at %84 giving the error "cooked: Read cdda : 
Input/output error". I experienced similar failure with KAudioCreator.
Any explanations to this?
This is 7.0-RELEASE running KDE 3.5.8.
Thanks!
