cd rom problems

[betty]

help !

i have 'lost contact' with my cd rom drive.
i tried putting in a new drive, although that was probably *not* the 
problem since the hardware browser still found the old drive.....
when i start up the computer it says something like 'cannot stat cd rom 
drive, no such device in fstab'

but here is the contents of fstab;
> LABEL=/                 /                       ext3    
> defaults        1 1
> LABEL=/boot             /boot                   ext3    
> defaults        1 2
> none                    /dev/pts                devpts  
> gid=5,mode=620  0 0
> none                    /proc                   proc    
> defaults        0 0
> none                    /dev/shm                tmpfs   
> defaults        0 0
> /dev/hda3               swap                    swap    
> defaults        0 0
> /dev/sda3               /exthdd                 ext3    
> defaults        0 0
> /dev/cdrom              /mnt/cdrom              iso9660 
> noauto,owner,kudzu,ro

i also tried to use this in fstab, but not help there either
