Just to eliminate the trivial first, your fstab line looks like this, right:

/dev/acd0c      /cdrom          cd9660  ro,noauto   0   0

(It probably does based on the "hints" below, but . . . )

I had an i7500 and now an i8000; my i7500 had the CD/CD-RW drive, and I never 
had any trouble with it.  Does it work under Windows?  Is there any reason to 
think that your drive (or disk) isn't just plain broken?

I don't have my i7500 any more (it was stolen, thus the new i8k), but the 
acd0 message for the i8000 looks like this:

69:acd0: CD-RW <TOSHIBA CD-RW/DVD-ROM SD-R2002> at ata0-slave using PIO4   

The PIO2 vs PIO4 and 0-slave vs 1-master are interesting.  It means that mine 
is on the same controller as my hard disk, and yours is on a different 
controller.  But I don't see why that would make it work or fail.
