Problem mounting USB cdrom

[Tunababa]

I have a problem mounting external cdrom of mine. I have edited /etc/fstab with the following lines added to it:

/dev/cdrw /media/cdrw iso9660 rw,user,auto 0 0
/dev/cdrom /media/cdrom iso9660 ro,user,auto 0 0

but have the following "boot messages":

Mounting local filesystems: mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

[FAILED]
Enabling /etc/fstab swaps: [ OK ]

after running dmesg | tail then, I have the following:

cdrom: failed setting lba address space
sr 4:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
sr 4:0:0:0: [sr0] Sense Key : Illegal Request [current]
sr 4:0:0:0: [sr0] Add. Sense: Logical block address out of range
sr 4:0:0:0: [sr0] CDB: Read(10): 28 00 00 00 00 10 00 00 01 00 00 00
end_request: I/O error, dev sr0, sector 64
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

I've tried all I can but this problem persisted; I have even tried to mount manually but the same error messages keep showing at the tail of syslog. My system is HP mini and I'm running FC13, that is newly installed. Other things work pretty well, other than I won't be able to listen to music. I need a help.
