The virtual hard drive that came with SIMH is a 55MB HP7920 disk drive. With just the O/S installed, there isn’t a lot of space left on this drive. This HP3000 can also emulate a 120MB HP7925.
This procedure will step you through backing the HP3000 up, creating an HP7925, then restoring the files onto the new hard drive. I’ve wanted to do this 2 times now, so I will write down the process for posterity.
SYSDUMP
You need to copy the O/S and all the files to tape. This is done with the SYSDUMP command.
Earlier versions of SIMH hung trying to do a SYSDUMP. I obtained simh-4.0-current–2019-05-07-52a31597.zip and extracted the hp3000.exe from it.

Create a SIM script file with the following contents. I will call this myreload.sim.
set -n console log=mpe-1-reload.log set console DEL=177 set cpu idle=10 set ds0 7925,format attach -n ds0 mpe.7925.disc set ms0 7970E attach -r ms0 sysdump-190825.tape deposit SWCH 003006 load assert 01.112247=046022 deposit 01.112247 021360
mpe.7225.disc will be the file containing the contents of the new HP7925 disk drive.
sysdump-190825.tape is the name of the tape file I just created above.
Now Start the HP using the new SIM script:
C:\hp3000Sim>hp3000 myreload.sim HP 3000 simulator V4.0-0 Current git commit id: 52a31597 Logging to file "mpe-1-reload.log" C:/hp3000Sim/myreload.sim-5> attach -n ds0 mpe.7925.disc DS: creating new file C:/hp3000Sim/myreload.sim-7> attach -r ms0 sysdump-190825.tape MS: unit is read only Cold load complete, P: 177661 (LOAD Q-12)
The last step is to remove the HP7920 from the configuration, add the HP7925, and once that is done, the system will load the tape onto the new drive.
Type GO to start the system and follow the example:

That’s it! On a real classic HP3000, that would have taken hours. I spent many a long night in my youth doing just that.
Just to check that everything is roughly correct:

The last step is to fix the SIMH startup script to use the new hard drive. Most likely you are using the mpe-auto.sim. script. Edit it and change 7920 to 7925 everywhere:
; Set the disc mode and attach the disc image file. set ds0 7925 attach -e ds0 mpe.7925.disc
