CDROM will not read CD's


My problem is as the subject line says the CDROM ( /dev/hdb , /dev/cdrom ) will not read CD's of any type music or data. There are two drives of this type installed on my computer a Plextor PX 708A DVD+R/RW (/dev/hdd/, /dev/cdrom2/, /dev/dvd/) and the drive above -a Sony CDU5221 CDROM reader. When a data CD is placed in this drive Nautilaus indicates that the drive is empty. At the command line I did a ls -l /dev/cdrom and got ->
lrwxrwxrwx 1 root root 3 April 15 12:09 /dev/cdrom -> hdd. I did the same on CDROM2 and got Ls: /dev/cdrom2: no such file or directory.
Below is a copy of my /etc/fstab:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/hde1 / ext3 defaults 1 1
/dev/hde6 /boot ext3 defaults 1 2
/dev/hdg1 /home ext3 defaults 1 2
/dev/hdb /mnt/cdrom iso9660 user,iocharset=iso8859-1,noauto,ro,exec 0 0
/dev/hdd /mnt/cdrom2 auto mask=0,user,iocharset=iso8859-1,codepage=850,noauto,ro,exec,users 0 0
none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,sync,codepage=850 0 0
none /proc proc defaults 0 0
/dev/hde8 /usr ext3 defaults 1 2
/dev/hde7 /var ext3 defaults 1 2
/dev/hde5 swap swap defaults 0 0

I am running Mandriva 2005 and gnome 2.8. I installed it yesterday(Mandriva 2005) and discoverd this problem this a.m. As stated above the DVD drive works o.k. -will read and play CD's. The CDROM works physically o.k. meaning the door opens lights work when media is palced inside it but doesn't read.

Any one who can give me some information on how to solve this problem will be appreciated.

Thanks
Chuck Parker

Thanks for your reply. If this is what you mean I am posting the results as follows: In a terminal as root

[chuck@localhost ~]$ su
Password:
[root@localhost chuck]# ls -l /dev/hdd
brw-rw---- 1 chuck cdrom 22, 64 Apr 15 17:39 /dev/hdd

[root@localhost chuck]# ls -l /dev/hdb
brw-rw---- 1 chuck cdrom 3, 64 Apr 15 17:39 /dev/hdb
[root@localhost chuck]#


The results /dev/hdd and /dev/hdb were highlighted.

Thanks for your reply - the answer is yes. /dev/hdd (dvd burner) works fine plays Cd's,data and music, and burns CD's. I haven't burned any DVD's yet although I have no reason to believe that it will not.

Where do I put the symlink ie what directory?

yes ,we usually have the OS making those symlinks by itself ,but when it does not do that on its own we need to do this way
