Dear friends:

I have two Atapi drive: one is a CD/CDWriter (/dev/hdc mounted on
/media/cdrecorder) the other is a DVD/CD drive (/dev/hdd mounted on
/media/cdrom). My DVD drive (dev/hdd or /media/cdrom) works perfectly. I
can play videos it, and I can also use it as a CD. I just transferred
data from a data CD to my Linux via this /dev/hdd. When I opened the
drive with my File Manager, it showed the contents of the drive, first
of my DVD movie, then of my data CD. And CD/CDWriter does correctly
record data. I used K3b and compiled a CD and burned it. But when I try
to read the CD after burning it, I can't. The contents do not show up.

I asked about this before. At first, I thought it was just a cosmetic
matter. I was getting an I/O error message for my CD/CDWriter and my DVD
during bootup. So long as the drives worked, that was fine with me. The
CD/CDWriter plays my music CD's, the DVD plays my movie DVD's. So far so
good.
However, although I installed my Scientific Linux system from data CD's
(using my , now it turns out that I cannot transfer any of my data files
from a data CD to my computer via my CD/CDWriter drive. I can only do it
via my DVD drive, whose contents show up correctly in File Manager.

The reason I had to use my DVD/CD drive to transfer my files to my
computer is that my regular CD drive (CD/CDWriter or /dev/hdc) cannot
read any of the contents. None of the contents show up in File Manager
or in the terminal. Please see below:

[sher@localhost ~]$ su
Password:
[root@localhost sher]# cd /media/cdrecorder
[root@localhost cdrecorder]# ls
[root@localhost cdrecorder]#

[sher@localhost ~]$ su
Password:
[root@localhost sher]# mount /dev/hdd
[root@localhost sher]# mount /dev/hdc
mount: No medium found
[root@localhost sher]# mount /media/cdrom
mount: /dev/hdd already mounted or /media/cdrom busy
mount: according to mtab, /dev/hdd is already mounted on /media/cdrom
[root@localhost sher]# mount /media/cdrecorder
mount: No medium found
[root@localhost sher]#

Here is my /etc/fstab:

[root@localhost sher]# exit
exit
[sher@localhost ~]$ cat /etc/fstab
# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0
/dev/hdd /media/cdrom auto
noauto,user,exec,ro 0 0
/dev/hdc /media/cdrecorder
autonoauto,user,exec,ro 0 0
/dev/sda4 /media/IOMEGA vfat
pamconsole,noatime,sync,fscontext=system_u:object_r:removable_t,exec,noauto,managed
0 0
/dev/fd0 /media/floppy auto
pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0
[sher@localhost ~]$

I do not have this problem in Windows (dual-boot), so I know it's not
the drive.

I imagine this is a software configuration issue. If so, how can I
correctly configure my /dev/hdc CD/CDWriter so it can show its contents
in File Manager.

Thank you so much.

Benjamin
