Help with Raw CD images? (input/output error)

[Ognjen Bezanov <ognjen@mailshack.com>]

Hey all, this is more of a general linux question.

I have an (audio) CD which want to make a raw image of. Searching google 
indicates that this command should do it:

dd if=/dev/cdrom of=/path/image.img

but everytime i try to use it i get:

dd: reading '/dev/hdc': Input/ouput err
0+0 records in
0+0 records out


Can anyone help me? what could be wrong? I was thinking maybe if I 
enabled taskfile access in the kernel this would fix it, but I dont 
know. Any help appreciated. Thanks
