It has 1024 cylinders, 8 heads (5 platters, 1 servo surface, 1 surface unused) The jumpers are set for drive D0. The .X on the left says the data-out line is terminated and the data-in is unterminated (Jumper=terminated). That's the normal setting. From left-to-right, the ...X signify drives D3, D2, D1, D0. Yours is set for D0. The last two jumpers should be IN. I forget which is which but one is for daisy-chain select and the other selects "latch select errors" or something. For normal ST506, they are set correctly. I've installed that drive with an Adaptec 2070A RLL control- ler and it formats to better than 100 MBytes. Good Luck. Jim Borza
