MSD wroteOne thing I am wondering about, how far would they go. Would they, for example, go as far as checking the serial numbers on installed applications or even windows to try and figure out if they were paid for or just torrented?
I very likely doubt that they will want to look at your files. The highest extreme case scenario possible is that they think you're a terrorist/pedophile and they want to inspect your laptop/hard drive but again, I extremely doubt that this will happen. In fact, I've never heard a live case where they checked someone's drive, or even on the internet!
throughout these 4 years I've traveled from outside E.U to inside E.U and never have they ever asked me to give airport security my laptop/external drive for inspection. at the x-ray scan, just get ready your laptop from the case and your hard drive and it'll all ok!
