   From what I've heard, HPFS uses the top five bits of the sector number
to hold the drive number, which produces the 64 GB limit.

   Simple problem, really -- use the READ CAPACITY command to get the
number of blocks (sectors), and use the 10 byte CDB if there are > 2^21
blocks, or the six byte CDB if there are fewer.
