Thanks so much for the good advice.
The DVD drive mounts perfectly well: I can see the files in the drive.
The CD cannot mount ("cannot read superblock") But is that because the
CD (i.e. "cdrom") is actually a CD Recorder? Both CD and DVD play fine
(audio and video). Perhaps I should just leave well enough alone?
Please see output of mount below:
[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]#
Should I consider the matter closed?
