Possibly (I don't know anything about the programme's internal 
workings): what I do know is that any attempt to run !Photodesk from 
HostFS brings up the error message 'Filing system does not support 
this operation'. A pity really; RPCEmu/5.XX running on a fast PC/Mac 
would be ideal for !Photodesk, given the memory and disk access

You can install !Disknight on HostFS, and it will fix HD4 disk 
corruption problems - I've done so several times and would recommend

Indeed: that's good. But as it seems HD4 is essential to run 
!Photodesk, which is my photo-retouching/image manipulation app of 
choice, it's a drawback for me.
