Does anyone know if it's a good idea to put an external hard drive in checked luggage on a plane? I'll be bringing my laptop with me, and I have an external hard drive about the size of a king of thick book. I can either let the movers pack it, put in my carry-on bag with the laptop or put it in my checked luggage. What's the best way to transport it? I want it to be as safe as possible, though it's all backups and nothing that I must have with me.
