I thought that I could just plug them in, but alas that doesn't work. I am able to read from the drives, however any attempt to write to the disk results in an H37 error #40 (I think) the one about write protect error. I feel it has something to do with the dual speed nature of the AT drives via pin 2 on the interface, but I am unsure of how to do it. I would appreciate any help in this matter. Thanks a lot, Wally Siddiqui
