-* Inputs:       none

-* Description:  The block table stores bad block info, including MDF+
-*               blocks gone bad over the ages. Therefore, if we have a
-*               block table in place, then use it to scan for bad blocks
-*               If not, then scan for MDF.
-*               Now, a block table will only be found if spectra was already
-*               being used. For a fresh flash, we'll go thru scanning for
-*               MDF. If spectra was being used, then there is a chance that
-*               the MDF has been corrupted. Spectra avoids writing to the
-*               first 2 bytes of the spare area to all pages in a block. This
-*               covers all known flash devices. However, since flash
-*               manufacturers have no standard of where the MDF is stored,
-*               this cannot guarantee that the MDF is protected for future
-*               devices too. The initial scanning for the block table assures
-*               this. It is ok even if the block table is outdated, as all
-*               we're looking for are bad block markers.
-*               Use this when mounting a file system or starting a
-*               new flash.
