 -----------------------------------------------------------------------------
 A FAT file system interface to the SD card on SHIMMER.
 
 Assumptions:
 
 Only one volumne is mounted at a time
 
 Code is not reentrant because only one scratch buffer is provided.
 
 Only supports SD cards formated as FAT16 (only Windows XP foramted cards 
 tested) *
