   <pedantic>The default format for a DOS 3.3/ProDOS 5.25" disk is 16
256-byte sectors per track, 25 tracks per side, or 143360
bytes/side. However, computer kilobytes are 1024 bytes in size, or
exactly 140K.</pedantic>

   <rant>Looks like some HD manufacturers might be starting to grow up
and list capacity in computer-MB (1024^2), rather than the larger
1000^2 size that inflates expected size. At least they've started
doing the same with monitors-- "17-inch monitor, 15.2" usable viewing
area" is the norm, after a few lawsuits.</rant>
