This has GOT to be on the way to becomming a new Urban Legend.  First, there
are no X-rays emitted by the metal detector.  Second, the electric field set
up by the detector coils is far too weak to erase a disk or tape.  There is
no appreciable magnetic field, and anyway, magnetic fields attenuate as the
FOURTH power of distance.

Now, having said that -- maybe I am just showing my ignorance since I have
never had any problems.  Are there any DOCUMENTED instances of disk erasure
by the walk-through metal detectors? (any reply that starts out "my friend
knows someone who..." will immediately be discounted as an Urban Legend).
