Didn't one of you around 10 years ago post about an early hard
drive... it was made of pipe with magnetic media on it. It was moved
and the people moving it didn't wait for it to stop spinning. Like a
good gyroscope, it refused to change direction as the turned it to put
it on the elevator. Flew out the window and did an auger job into the
ground. I know its not a hard drive, I just don't remember what it is
called.
