As a computer repair tech myself, I can honestly say I have only EVER looked at a client's data when they've specifically ASKED me to double check that something is on the old/new drive, and then I double check that they want me to do this before doing anything. I have cloned countless drives, and besides them asking, I've never bothered to check anything, never cared to. Just clone, swap drives, we're done. So, while they CAN look at your data all they want, I can't imagine why they would. Not only would it be bad for business (get them sued/put out of business for good if they were to do something with your data after you trusted them with it), but it would also probably blackball them and THEN run them out of business. lol. I'm sure you're just fine!
