Or FLX. FLX 2.6 uses DJGPP and runs on old stuff, possibly as far back as actual DOS and certainly should have no problem with XP. It doesn't do image copy, though. You could steal some of the code and make an image copy tool. Or you could use it to initialize the destination disk, copy all

I'm not sure if the hub is an RP04 style or RP03 style. Yes, the accessories say big pack. Given that there is also a tool for looking at 5-ish platter packs, RP04 and later (with the smaller tool used for RM03 packs) is plausible. I remember seeing one of these in use, for inspection not
