RETRACTION...
I made the association because this is the second hard drive to develop bad
clusters in as many years. It also coincides with when PHL and other
airports started making me put the laptop through the xray.
It very well could be the MAD. I fly America West/Continental a lot, and
the MAD is very close to the xray at PHL Terminal "D".
Thanks Denys for the eye-opener.
