+ NOTE: No known dump exists of the formatter utility and the
+ format of the custom partition record (block 0) that the card
+ expects has not yet been determined, so this is largely untested
+ and will work only with a drive dump from real h/w.
+
+ PLEASE use it only on a backup copy of said dump and contact MESSdev
+ if you have one!
+
+ Partition block format:
+ +0000: ASCII "Zip Technologies"
