I know that the x ray machine won't damage my ipod Classic but am wondering about the tests that security staff sometimes do on electronic items. A few years ago, going through Stansted, security did what we think was a random check on a G3 ibook. The test involved the man wiping a cloth over the ibook which was testing for explosives. We then had to turn the ibook on and let it power up and then shut it down. I did ask if there was any chance that we could lose anything on it and was told no. I'm thinking that the hardware in ipods might be more sensitive and so am asking if there's ANY chance that the same or similar test/s that were done on our ibook could do anything to my ipod classic. We're going to Portugal in a few weeks going through Dublin on way out and returning from Faro.
