For diskspan:
You have to edit Records.ini file
Code:
[Record1]
Type=Freearc_Original
Source={src}\Data1.bin.001
Output={app}
Disk=1
Make records.ini internal if you wish to not use it alongside Setup.exe (it will be extracted to %temp% folder then).
For the hardware issue:
I'm about to fix this. Have some brain breaks atm
