asks what that extra I/O operation is that occurs a second or so
after writing to his hard disk.

     Are you *sure* it's not the cache being dumped?  This is a
file system function which happens on every Amiga disk drive (hard
or floppy) that I've ever seen.  That this is what you're seeing
is confirmed by your report of extensive disk activity on a re-boot
where this final I/O wasn't performed.  Without that final write to
flush the buffers, the disk is left in a compromised state.  That
extra I/O on re-boot is just the disk-validator cleaning things up
again; you're fortunate that it was able to do so without putting
up all sorts of nasty requesters telling you to use DiskDoctor (ugh!).
