...and I've had 360K and 720K drives as well.  XP gets a bit uppity 
though, if you try to format a 360K or 720K (or, IIRC, 1.2MB) drive.  
The code's still in the driver, but someone at MS decided that /F:360 
etc.  shouldn't go into the command itself.

Should you happen to get your hands on some NEC 9801 DOS-V 1.3MB 3.5" 
diskettes,Windows should read them just fine if they're used on a 
Superdrive or most USB floppy drives.  Formatting is another matter,
