The Amiga RDB structure uses a (not very deep) tree of blocks, with the
root block being anywhere from block 0 to 15, including, and pointing
to three linked lists, one of partion descriptor blocks, one of=20
bad block table blocks, and one of file system header blocks, which in
turn point to a linked list of code blocks each.
You can't know what blocks are free unless you have parsed this stuff.
