I had to create the block device for SCSI because there was none; no /dev/sr0,
/dev/sr1, etc.
And I already had /dev/cdrom linked to /dev/hdd. Seemed reasonable to point
/dev/cdrw to the device that the cdrw was on. They're only soft links after
all... But you are right, I don't really need them.

This is what I wanted and tried to do initially and couldn't access either
drive. Which is why I ended up pointing both to /dev/sr0 and /dev/sr1.
Maybe I should start over?

dmesg output:

Ok there

OK so I backed up per your suggestion and did the following:
/dev/cdrom -> /dev/hdc
/dev/cdrw -> /dev/sr0
Then rebooted.
Now when I try and mount the cdrom:
$ mount /dev/cdrom /mnt/cdrom
/dev/cdrom: Input/output error
mount: you must specify the filesystem type
So I tried:
$ mount -t iso9660 /dev/cdrom /mnt/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
When I try and mount the cd-writer:
$ mount /dev/cdrw /mnt/cdrw
mount: block device /dev/cdrw is write-protected, mounting read-only
But it mounts the first cdrom on /dev/hdc !!! This is what confuses me...
TIA (very much)
