You need to specify GEMDOS HD drive letters that do not overlap with 
partitions on your configured drive images.

Multi-drive GEMDOS HD support itself is a niche use-case, to make it 
easier to test multi-drive support in file managers (e.g. desktops), and 
to duplicate multi-drive desktop setups from original machines.

Coupling that with images is much more niche, one where user is expected 
to know what drives GEMDOS HD partitions should use...

Remember also that you can have multiple Hatari configs for different 
setups (one for ST, one for TT, one for Falcon, one to duplicate you 
original desktop, one for HD Driver testing etc). Just give Hatari a 
different config file with "-c" option from command line, or put those 
into desktop shortcuts...
