If they're the standard DD floppies, yes.
This must be the one you're talking about.
ebay auctionHowever, he said this
For Sale: 2 Amiga 3000 floppy drives. Pulled from a working Amiga.
Items are in good physical condition but is sold as-is since I cannot fully test them
Looks like he's parting out an A3000, that sucks. If he pulled them from a working A3000, why doesn't he know if they work? Too bad he doesn't have a picture.
That means that they have no faceplate. It'll look rather ugly on your A2000. And the special eject button means that if you use a normal drive face plate you'll have to cut a wider hole.
edit, he he, you guys are fast. :-)
