"Several years ago I replaced a faulty hard drive on a server. I
had a lady complain that nothing was faster, despite expecting it
to be so. I asked why she was anticipating a change in performance
and she replied, "Didn't you just change the hard drive?"
"I didn't twig just what she meant at the time. It took several
more experiences with people telling me their "hard drive" kept
crashing (which concerned me greatly until I realised it was just
Microsoft Word that was locking up) or even asking if they could
bring in their "hard drive" from home and have me fix up a few
problems."
