Answers: In my case, I rebooted after unsuccessfully trying to kill the
process.
i) The majority of people said that, in their experience, a reboot was how
they "fixed" this problem.
ii) Power-cycling the tape drive, repeatedly trying to kill the process
while the drive is both off and on.
iii) Also, loading a scratch tape into the drive and trying to bring the
device back online, in the hope the process will pick it up.
