I have some disk images that were used in UAE (Amiga Emulator) and I
want to write them to floppies in Amiga format. So in a perfect world
I would click a file, drag it onto a floppy (Amiga formatted - but if
the utility formatted it too, great!) and take that floppy and plug it
into my antiquated Amiga 1000.

What type of disk drive / utilities do I need to accomplish this?

Hardware:

i-Mac, 1.25ghz, 17" LCD, 1 gig ram, 80gb hd
Amiga 1000, 1mb of ram, 1 floppy drive
also an Amiga 500, 1mb of RAM, 1 floppy drive.

Any help would be appreciated!
