# mount /dev/sg0 /mnt/cdrom -t iso9660
mount: /dev/sg0 is not a block device

I have 2 IDE cdroms (one is a cdrw).
Both are recognized in xcdroast.
I can't find them to mount though.

# mount /dev/sg0 /mnt/cdrom -t iso9660
mount: /dev/sg0 is not a block device

# mount /dev/sg1 /mnt/cdrom -t iso9660
mount: /dev/sg1 is not a block device

# mount /dev/sd/c1b0t0u0p1 /mnt/cdrom -t iso9660
mount: wrong fs type, bad option, bad superblock on /dev/sd/c1b0t0u0p1,
       or too many mounted file systems

# mount /dev/sg/c0b0t0u0 /mnt/cdrom -t iso9660
mount: /dev/sg/c0b0t0u0 is not a block device

# mount /dev/sg/c0b0t1u0 /mnt/cdrom -t iso9660
mount: /dev/sg/c0b0t1u0 is not a block device


I've tried everything (except the one that works).
/dev/sda1 is a USB Smart Media reader (is sda1 the same as sg2 (which is 
the same as sg/c1b0t0u0?).

I have 2 IDE cdroms (on cdrw and one cdr).
I want to mount them both but there is are no devices for either.
I added "hdc=ide-scsi hdd=ide-scsi" to grub to make them both show up in xcdroast.
I still want to read from one outside of xcdroast, right now it seems mutually exclusive.
