I didn't know there were any disks that old, or, rather, that small.
Really, 64-byte sectors?  I didn't think even floppies did that.  What
hardware are you using them with?  (I was happy when I found a floppy
drive that uses 256-byte sectors at the interface; I'm saving it not
for use as a floppy drive but for use as a non-512-byte-sector drive.)
