Wow this is primative but great - I’ll take it.
Tried it once and it seems to work.
on a Mac use FATsort (it is a terminal executable - so you will need to use the terminal)
This page explains how to use it. (see first post on the page)

If you move the fatsort executable to /usr/local/bin/fatsort you will only have to run
fatsort /dev/<devicename>
to re-sort the internal or external microSD
the devicename would be the mountpoint of your Sports internal or external disk.
to manually find your device name run OS X diskutillity and select your micro SD disk from the list and then get The “I” (info) on the menu bar. It will give you the mount point.
Someone (SanDisk?) could write an Apple Script that finds your Sports device names and then does the FATsort with one click.
