X-rays could probably erase flash cards given a high enough dose, but even the highest-power airport X-ray machines don't give them that much. > I would think the magnetic domains in a laptop disk drive would be more > sensitive than flash memory. Not to X-rays. Old airport X-ray machines had a reputation (justified or not - I don't know) for leaking magnetic fields from the X-ray generator, but I don't think modern ones do, and in any case hard drives include magnetic shielding that should protect them against any ordinary fields. For some real damage, you need something like the USPS e-beam machines: http://www.i3a.org/pdf/i3a_titan_testing_report.pdf Unprocessed film, mere erasure of media? Pfeh! How about "Severe yellowing of flash lens viewfinder lens and camera lens. Camera failed to power up after test." "Inkjet prints on HP glossy photo paper: Slight yellowing of images; strong, objectional odor described by everyone present as "burned", by-product chemistry unknown; impact on long" "Compact Flash: ... the card is irreparably damaged and cannot be used." etc. John -- John DuBois [EMAIL PROTECTED] KC6QKZ/AE http://www.armory.com/~spcecdt/ * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
