Re: I remember floppy disks
The Apple DOS 3.3 approach to the drive motor is one of the smarter ones, in my opinion: turn motor on, inspect the disk shift register. If it is still shifting, the disk is obviously still spinning fast enough from whenever the last time the motor was on, so continue. Otherwise wait for spin up. When done reading a sector, switch the motor off again (subject to a hardware 1-second delay).
