Very strange--I go through the process you described quite a bit, and I've
never seen this happen.

Do you have any desk accessories that are opening files for read/write
access (not just Read) and leaving them open?  If so, the ProDOS FST
doesn't necessarily write out new bitmap blocks to disk until all the
read/write files are *closed*.

That means if a file is still open for writing and you force a reboot
with Apple-Ctrl-Reset (instead of shutting down nicely), you're in
trouble.

But the system software doesn't leave files open for writing (it keeps
Sys.Resources open read-only).
