Let's make sure what you are asking. I think you want to run DW3 on a PC and 
HDB-DOS on either a Coco1/2 or Coco3. Since you mention HDB-DOS, you want to 
work under Disk Basic not OS-9.

Yes, you will need to have the appropriate HDB-DOS for Drivewire on the CF card. 
That must be loaded as the disk ROM. That is not the same ROM as the stock 
HDB-DOS used with the CF card VFD images.
Now if you mean that a VFD is the same as a MESS or VCC .vhd image, you can 
certainly mount them in DW3 if you have some on the PC. You may have trouble 
moving a VFD from the CF card to the PC unless you have a card reader on the PC.

There are some issues with using VFD images partitioned for both OS-9 and Disk 
Basic with DW3. DW4 permits setting an offset value for the Disk Basic partition 
which DW3 can't do. Without that, you would need to POKE offset values into 
HDB-DOS for Drivewire or edit the ROM.
