Maybe it’s worth asking him to assist in person to your repair, so that you don’t leave him with your datas alone. This could be counterproductive for opsec reasons anyway.
I have seen that some of the services that offer data rescue in my country offer just such a service - means that the client is present when rescuing data (which of course means a higher price). Yet even in such a situation, is it possible to be 100% sure that the data is being copied to only one location, and that this person is not doing another secret backup simultaneously?
i never leave any old or failed disks anywhere or in anything i giveaway or sell. the drives are destroyed. even if it dies when in the warranty period im not sending a drive back for a replacement so i just write it off.
Exactly what I do all my life, I never sell or throw away old computers or mobile phones. I still have my first cell phone over the age of 20 which was state-of-the-art technology at the time, but quite inconvenient to carry because of its size and weight - who would say that today's smartphones are even bigger and similar in weight
