Dear friends:
I have two CD drives: "cdrom: and "cdrom1". "cdrom" is also a CDWriter. "cdrom1" is my DVD player. Both of them work fine: My music CD plays fine in KSCD and my movies play fine in my DVD drive. Yet, there is a definite I/O problem with both of them. Please see screenshot:

Bootup confirms that both hdc and hdd, that is, "cdrom" and "cdrom1"have failed the test and that they have an I/O problem.
I have no idea what this means. Does this have anything to do with IRQ? If so, how should I try to solve this.
There are jumpers on the CDROMs that let you set up the drives as master and slave. Since the drives seem to be working and are recognized as hdc and hdd, I doubt that is the problem.
The only things that I can think of are for the cables being defective or loose. Another possibility is that having both CDROMs on the same controller stresses the IDE controller on your system board. I had an old Memorex that loaded down the controller heavily, making both devices fail.
Check the jumpers on the drives and set one to master, check cables. Try one connected at a time and see if the errors are specific to either device.
Just a few things that I'd try.

Thank you so much.
Is it normal for bootup to say that hdc and hdd have failed? Is there a way to correct this for both hdc and hdd. Is this a matter of IRQ?
I then decided to edit /etc/fstab. Here is the old version:
[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/sda4 /media/IOMEGA vfat pamconsole,noatime,sync,fscontext=system_u:object_ r:removable_t,exec,noauto,managed 0 0 /dev/hdd /media/cdrom auto pamconsole,fscontext=system_u:object_r:removable_t ,exec,noauto,managed 0 0 /dev/hdc /media/cdrecorder auto pamconsole,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 tried. Rebooted but I still saw the "Failed" comment about hdc and hdd during bootup.
Would appreciate your help.
Thank you.
