Except if you have an old 5.25" DSDD drive.  Each time the motor
starts up you have to wait 4 seconds instead of 2.5 seconds.
If you can type the next command before the 2 second motor off
timeout expires it does work quickly!
Despite this I still prefer DR-DOS because it's memory management
works better than MS-DOS.

My guess is that it is an attempt to save time if the floppy is actually
needed on a later transfer.
