Ok, then mounting it should work.

I sometimes get error reports like this as well with USB sticks. I can usua=
see it on the drive as well, the drive's indicator light doesn't light up.

Pulling out the USB cable and trying again usually helps, in my
experience. Try another cable or another USB port if available. Sometimes it
is necessary to use camcontrol(8) as per the earlier reply.

The USB stack in 7.2 doesn't always handle quirky hardware well. There could
be a regression on your hardware going from 6.x to 7.2. The USB stack
has been rewritten for 8.0. In my limited testing it works better. I've got
8.0-PRERELEASE running on a laptop without problems.
