My memory fails on the details but you need to research the various FAT16
'disk' formats.  You're probably reading a partition block which will have
to be parsed in order to locate the actual boot sector.  Sorry I can't take
the time to help more.  I had to deal with this once when reading SD cards
via USB.

  Subject: [lpc2000] SD card boot sector location


  Hi all,
  I have an SD card formatted by means of a PC card reader. When I try to
access the card via SPI, it seems that the boot sector's number is 249. All
sectors below this location read as zeroes. The card's volume is 1 GB. The
file system is FAT16.
  The question is: why 249 ? It must be described somewhere, but I failed to
find anything in "ProdManualSDCardv1.9" and some other documents.
  Regards,
  Max
