The Amiga drive is double-sided, and NOT flip double-sided. It works, I suspect, like an IBM PC drive, alternating tracks on one side then the next (two r/w heads.) Thus the drive is 880K. The Atari 530ST, on the other hand is something like 360K per side, and you must physically flip and notch in holes I suspect to get the amount Atari advertises. ----------------------------------------------------------------------- d. rosenberg on Murray Hill /\ at ATT/BTL uucp: ..!ihnp4!alice!aer -- mail subject TO DAN My opinions are my own. -----------------------------------------------------------------------
