Thanks for your answers.
I did know parts of that.

My aim is to make it as foolproof as possible. I do not know who will operate that, so it should be as easy as possible with little to no possibility of error. Command line commands are not the preferred choice for that.

Therefore I would like a little software doing all the things like formatting and writing and verifing the data. To be on the safe side of retrieving the data, it would be very important that the software creates a database with all the archived files as a searchable catalog.

It can be on a MAC, but PC would be the better choice.
