unplayable audio CD

[Frank Shute]

I just bought a couple of audio CDs.

One works fine and I ripped and encoded it with Grip.

The other is problematic (Grip shows no tracklist):

$ cdcontrol status
No current status info available
No media catalog info available
Left volume = 255, right volume = 255

$ cdcontrol info  
cdcontrol: getting toc header: Input/output error
cdcontrol: Input/output error

$ cdcontrol play 1
cdcontrol: Input/output error

$ echo $CDROM
/dev/acd0

But the tracks are listed in /dev:

$ ls -l /dev | grep acd

crw-r--r--  1 root   operator    0,  85 Nov 30 23:27 acd0
crw-r-----  1 root   operator    0,  91 Nov 30 23:27 acd0t01

I believe I can dd the tracks (can somebody give me an example
command? I don't know what blocksize to use) and then encode although
it's all a bit painful compared to using Grip.

Any suggestions gratefully received.
