Mark --

FWIW, my experience with defragmenters is limited to DiskExpress on the Mac.
This is a system extension that monitors file activity (presumably by
intercepting OS calls).  Files are then moved to the front of the disk if
they're frequently used and to the back if dormant.  In between is the free
space.  All this happens automatically once a day (if the computed
"fragmentation index" falls below a user-defined value).

I'd say the penalty of having a concurrent system extension trapping all my
disk I/O calls is much more than offset by the dramatic increase in performance
(reduced seek times).  The system has yet to generate an error and is able to
cope with power failure while operating, since it only moves one file at a
time.

Any plans for dynamic activity monitoring?  In any case, I'd like to know how
to order SpeedDisk from the UK.
