Thank you, I understand and used to know how to set up and change floppy address. It is not that simple, yes it is the same problem. I am using the amigakit floppy you gave me during a install of a new Cd card hard drive the floppy kept erroring. I traced it to the ribbon cable, so I swapped one from the 4 A2000 I have, I am using the differant floppy S, cables jumpers, nothing will make both internal drives work. I had them in storage for a few years yes but I upgraded the roms to 3.1 and a new WB. Your old floppy worked for a little and now the drive busy light flashes just once every minute or so. If I hook both up jumpers in ds1 ds0 jumper on 301 and both busy lights stay on or both drives do not do any thing. Bad Gary chip? Paula I remember that one shares controller duties. Just a guess but if I use a new cable from amigakit maybe my issues will go away. The trouble seems to go to any Amiga I use, I have 3 real floppy S and yours and all fail on any machine.
