What is MOD disk?  Magneto-Optical?  If so I need info on the hardware that connects the MOD to the system (SCSI - id so what controller...)

Yes it is magneto-optical, it connected to SCSI controller. SCSI id it is showing 4.

Was this drive always in this machine?  Were the MO disks created with this machine?  

Post the contents of:

And run "hwconfig" to see if it actually sees the drive

You could run:
"scoadmin filesystem manager"  from th command line to see if a mount point was defined for the drive.

More questions than answers, I'm afraid.

I guess we need to know what type of filesystem is on the MO media.  

You could try running divvy on the second and/or third drive (one of them should be the MO)

divvy /dev/rdsk/1s0


divvy /dev/rdsk/2s0

Don't make any changes - we just want to see what filesystem(s) are on the media.

some more information about MOD drive scsi details (i got this info by pressing 'CTRL A" key while booting. pc)
after pressing CTRL A it is showing two options
1. 29320    A at Slot 04 03.09.00
2. 29320     B at Slot 04 03.09.01
if i select First option and scsi tools than
it is showing SCSI ID 4  SONY SMO F551 (this is my MOD Drive)
and               SCSI  ID 7 Adaptec 29320
If i select Second option and scsi tools than
it is showing SCSI ID 0 Fujitsu MAP3735NP (it is my HDD)
and                SCSI ID 7  Adaptec 29320

i think above information usefull for finding disk details in Sco UNIX.

Do you have some media for the drive that you do not care about?  So we can play without risking important data.  I would like to run "mkdev hd" to see if we can find the device name and take a peak, it is dangerous though - data loss is possible if we go too far.

Ok experts...

and is it possible to read mod data...

Linux should see the drive as /dev/sdX  - X could be a,b,c...  

It SHOULD show up as /dev/sdb  (/dev/sda should be the SCSI hard disk)

Then just try:

mount /dev/sdb /mnt

See if that works.
