Hi all. In 2 days I'm heading off to the US and Canada for 8 weeks, for the most part I will be traveling British Columbia and in parts Alberta. Although snowboarding is the primary focus of the trip, photography will be a significant part as well. My plan is to pick up 2 perhaps 3 16gb class 10 sdhc cards to compliment the 32gb card I already have. I will be shooting a bit of video and trying my hand at time-lapse stuff....so as you could imagine, I need gigabytes !!! I have a 300gb Western Digital Elements external hard drive....nice and compact and reliable performance.my question is: Are there any issues with data integrity when passing through the various airport scanners ? I'd hate to go through an X-ray and blitz all my images !!!! I can't find the original box nor any literature online regarding such issues for the unit I have. If I know the hard drive in question is prone to data loss/malfunction I will just buy another....but I'd rather not if there is no need. Thanks in advance.
