Fairlight-CMI

can anyone post the exact commands in 9.34 for 
partitioning and formatting each of up to 
four external 4GB SCSI HD's ?

I've got four Seagate Barracuda SCSI-2 4GB HD's connected to
my Rev 9.34 CMI's External SCSI connector on the rear of my chassis.

The four hard drives are set to SCSI ID's 4,5,6,7
External SCSI active terminator is plugged into the end of the SCSI
chain at the last drive.  The jumpers at each drive for on-board
termination are disabled, I'm using the external terminator plug.

at CMI boot, the diag screen shows the detection of the 4 external
SCSI devices 4,5,6,7 in addition to the internal SCSI devices 0 
(boot HD) and 1 (tape drive).

what are the names of the external SCSI drives to CHD to ?
I've tried 
"CHD /SC400"
"CHD /SC500"
"CHD /SC600"
"CHD /SC700"
but get Error #222 - Device Not Found

I don't seem to have a command called "INQ"
my Partgen command is v1.04
my DiskPart command is v1.01
my DiskInit command is V2.00

please help !
