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 "cdrom" and "cdrom1". Please see screenshot:
Sounds like you have /dev/hdc and /dev/hdd set up to mount on boot. Unless you have mountable disks in the drives during bootup, the system will report errors.
Check your /etc/fstab. For the two drives, you should have entries similar to these:
/dev/hdc /mnt/cdrom auto ro, noauto, user, exec 0 0
/dev/hdd /mnt/cdrom1 auto rw, noauto, user, exec 0 0
With these settings, the system is aware of the drives, but doesn't try to mount them on boot, but will mount them when called (when there is a disk in the drive).
I replaced the settings in my fstab with yours and they didn't work, but perhaps it's all because these are read-only CD/DVD drives. The output below tells it all:
[root@localhost sher]# mount /dev/hdc /media/cdrecorder
/dev/hdc: Input/output error
mount: block device /dev/hdc is write-protected, mounting read-only
/dev/hdc: Input/output error
mount: /dev/hdc: can't read superblock
[root@localhost sher]# mount /dev/hdd /media/cdrom
mount: block device /dev/hdd is write-protected, mounting read-only
mount: /dev/hdd already mounted or /media/cdrom busy
mount: according to mtab, /dev/hdd is already mounted on /media/cdrom
[root@localhost sher]#
Since they both drives are working fine, do you think we should just consider the matter closed/
