Hi, 
fstab has the following...
/dev/cdrom  /mnt/cdrom   iso9660 noauto,owner, ro 0 0
tried mount with following commands...
mount /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
mount -t iso9660 /dev/cdrom /mnt/cdrom 
ls -al /dev/cdrom >returns   lrwxrwxrwx 1  root  root   8 may 13 20: 40 /dev/cdrom -> /devhdd
cat /proc/ide/hdd/model  >returns   CD-RW IDE5232
dmesg |grep -i hd
there is a lot of output from this commend to much for me to type all but here is  some
kernel command line still has hdd=ide-scsi at the end of it even though this has been removed from grub.conf I have checked that.
hdd: CD-RW IDE5232, ATAPI CD/DVD-ROM drive
hdd: attached ide-scsi driver
hdd: dma disabled
ide-scsi: hdd: unsupported command in request queue (0)
end_request: I/O error, dev 16:40 (hdd), sector 0
there are 6 of these  each for a different sector ( 0,2,4,6,0,64)
fdisk -l >returns  
/dev/hda1   *  1     13    104391          83 linux
/dev/hda2      14     46    265072*       82 linux swap
/dev/hda3      47    9729  77778697*   83 linux
 any suggestions, this is a new install of version 6.0
