Thank you so much for the very prompt response. You answered my question on a Saturday… wow! I also appreciate greatly you sharing your expertise and insights with me.
So, it seems that my only option is to encrypt the data on the external hard drive. This brings up another question that I would like to ask you.
I have a backup of some files on that external hard drive; backup occurs once a month. In the above scenario, that backup would be encrypted. Therefore, I’ll have to decrypt, do the backup, then encrypt again; am I right?
And by the way, approximately how long it would take to encrypt 300 GB of data; it would take the same amount of time to decrypt?
