I travel a great deal and my CD’s take some terrible abuse. I have cracked disk, broke them had them roll around airport terminals you name it. So I travel with copies of the originals when I can or at least a ISO on my portable hard-drive so I don’t get stuck. If you travel International I do not recomend this, as I have had to provide proof to customs that I owned the orignals when my CD case was inspected once and the agent questioned whether they where pirated or not which cost me a trip back to the airport. But some disk are a pain to copy. If you have a disk that is hard to copy I recommend you try Alcohol 120%. [TechTV]
