Thanks for the info! That explains something I think I saw posted at a local BBS that was supposed to make the 2000 think the external drive was the second internal drive. If such a hack exists, maybe you would find it useful... maybe someone else could comment, 'cause not being a 2000 owner, I didn't pay much attention to it at the time. More to the poster who was interested in the HW hack to put external drives on whatever machine: if you can't find it locally, I'd be happy to send you a disk w/ it and my notes on making it work (the 5.25 drive I got didn't like the amiga's timing...)
