I have 500 GB of data on a Hard disk.
I am going to carry one copy of that HD with me in carry on luggage in my flight.
But I would also like to send another copy of the same HD to USA either by post or thru a courier as a back up just in case something happens to the HD I am carrying with me.
How safe the second HD would be if I protected it with an OS password ? If someone gets hold of it, can they open that HD ? If yes, how do I send it by Post so that the data will be protected ?
Thanks
