I haven't used RH for a couple of years--before the days of autmounting
stuff, or at least toward the beginning of that trend. Isn't 4 the very
latest release? Distros that have come out in the last year or so,
especially those that use the 2.6.x kernel, seem to all be using some sort
of virtual filesystem and often do automounting of inserted media and mass
storage devices. Might not your RH version be one of these? Did you
recently post something indicating your distro is using LVM? I'm guessing
the system automounts that drive when you insert it. Have you searched
around the system for indications that it's already mounted and/or its
mount point? I'd kind of doubt that with such a recent distro you'd have
to do any manual mounting. But this is somewhat circumstantial: as I said,
I haven't used RH for a couple of years or so (since 7.3).
