Here's what I use to read data CD/DVDs: 

[jep@example.com jep]$ cat bin/readrawcd
#!/bin/sh
device=$1

blocksize=`isoinfo -d -i $device | grep "^Logical block size is:" | cut -d " " -f 5`
if test "$blocksize" = ""; then
   echo catdevice FATAL ERROR: Blank blocksize >&2
 exit
fi

blockcount=`isoinfo -d -i $device | grep "^Volume size is:" | cut -d " " -f 4`
if test "$blockcount" = ""; then
    echo catdevice FATAL ERROR: Blank blockcount >&2
        exit
fi

command="dd if=$device bs=$blocksize count=$blockcount conv=notrunc,noerror"
echo "$command" >&2
$command
[jep@example.com jep]$

I use it like: 

   readrawcd /dev/cdrom | tee foo.iso | md5sum >>MD5SUM

Sometimes I need to turn off read ahead: 

   hdparm -a 0 /dev/cdrom ;# (I'm not sure about the -a 0 part, so RTM)

Mount like: 

   mount -t iso9660 -o loop,ro foo.iso /mnt/foo
