[Simh] Interdata OS/32 - adding disks

[Don Stalkowski]

I tried adding a couple of large disks by creating a new configuration
file from OS32MTS1.SYS and changing the following lines:

41    DSC3:,FC,52,SELCH=F0,CONTR=FB    * 40-MB DISK (REMOVEABLE)
42    DSC4:,FC,53,SELCH=F0,CONTR=FB    * 67-MB DISK (REMOVEABLE)
43    DSC5:,FC,54,SELCH=F0,CONTR=FB    *256-MB DISK (REMOVEABLE)

to

41    DSC3:,FD,54,SELCH=F0,CONTR=FB    *256-MB DISK (REMOVEABLE)
42    DSC4:,FC,53,SELCH=F0,CONTR=FB    * 67-MB DISK (REMOVEABLE)
43    DSC5:,FE,53,SELCH=F0,CONTR=FB    * 67-MB DISK (REMOVEABLE)

The change is the device addresses and types in lines 41 and 43.

The sysgen went ok and when I load the new OS, "D D" shows DSC3 and
DSC5 on the new addresses.

However, when I try to initialize DSC5 I get:

sim> set dm1 msm80
sim> att dm1 dm1.dsk
sim> c
L FASTCHEK
TSKID = FASTCHEK
*ST ,INIT=DSC5:,VOL=USR,LI=CON:

*11:25:47   FASTCHEK:END OF TASK    10                        

When I try DSC3 I get:

*Simulation stopped, PC: 22CBA (BAL R12,19084)
sim> set dm2 msm300
sim> att dm2 dm2.dsk
sim> c
L FASTCHEK
TSKID = FASTCHEK
*ST ,INIT=DSC3:,VOL=USR,LI=CON:

; lots of output...

*11:26:47   FASTCHEK:DEFECTIVE SECTOR AT 0014FF  (CHS=004/07/3F) STATUS 8
*11:26:47   FASTCHEK:DEFECTIVE SECTOR AT 001500  (CHS=004/08/00) STATUS 8

*11:26:47   FASTCHEK:END OF TASK    22

Any suggestions?
