I recently bought a used STacy and the 20 meg drive was dead. I tried to swap in a Quantum Pro LPS drive (270 megs I think) and the STacy won't even recognize it. I tried a 2.5 gig drive, too but was 99% sure that the controller wouldn't be able to support it. Does anyone know of the limitations on the controller? Are there any specific parameters one must stay within when swapping the drive as far as cylinders/heads or size? Any help would be appreciated!
