I'm told that my script to keep "FreeAgent" USB external drives from

have *not* verified that (having none and no time), but if you want the
script to try on your own, I think I posted it here, or could put it up
on request.

That would be great! I would definitely like to have a script that keeps drives alive. Can you send it privately (keep the list archive smaller) or put it on the net?
This is the version I posted, I've played with some extra features, but
since you may want to modify it, simple is best. It's small enough to
just send.
