[text deleted > > Hope that helps Yes it helped! Thanks. The jumper wasn't called J3 though. There are two jumpers next to the cables that go to the drive and they are calld PL8 and PL9. I tried out every combination of setting and it worked with BOTH jumpers changed. Does someone (maybe from Acorn?) know if that's ok? The problem wasn't solved completely because the drive should have 88 Meg capacity. After formatting with 17 Sect/Track, 9 Heads and 1024 Cylinders (The controller cannot cope with more that 1024, I think. The drive has 1073 cylinders), I had about 40 Meg free on the drive. Where is the rest??? I tried to format the drive with 32 Sect/Track and it worked. But this is probably not advisable to do. Any ideas? > Bob > > -- > Robert J.
