so is all ok now?

I'm not sure how to deal with the changing drive letters for Windows. If it were a mac it would be different because you could name/rename the actual external drives & that's how it would read it afaik (eg: Lord's Flash LW volume). Windows has such an archaic technique ... excuse my comment but, still loosely based on DOS.

I wonder if it would make a difference with the order in which you connect the flash drives. Example if you always connect them in same order, then windows will see them connected to same drive letters. eg: Connect the one with LW's files on first always .. or 2nd always, etc. And likewise LW will not get confused.
