A while back, I needed to share my external Seagate HD across a small
network and I wanted a bit of security. That function is no longer needed.
Now, I want to be able to plug the HD into any computer without having to
fuss with permission, and not have to fuss with access control (for the HD).
I don't want to mess with the networking settings on those computers. These
are guys in my band, so trust isn't an issue, and I'm walking away with my
HD when I'm done giving them tunes.

Or, to put it another way, I want the HD to behave like it did when it came
out of the box. Not sure how to revert to that state. What's happening now
is that when I plug into any machine except my own and try to access the HD,
I get a "Not accessible" msg.

On my own computer, if I right click on this external HD, choose properties,
and then the Sharing tab, I see that "Share this folder" is selected, and
there's a share name, E$. If I simply choose "Do not share this folder",
will this accomplish the necessary goal?
