Barry’s is a dammed good cuppa tea, but Yorkshire tea is the English equivalent. God speed, and all the best in your new life. Having just moved my family to the other side of France, I can empathise as to the effort and stress involved in such an endeavour.

I work for an it department who resells their old stock online, we scrub the disks before sales, physical destruction is not possible.

It won’t stop “anyone”, I’ve been lead to believe there are ways even after a single pass, to recover data. if I had anything to hide, I would use a physical destruction method, nothing else

Use shred , it will automate multiple random passes, and finish with a zero pass.

Look at someone who is cold, their lips are blue, someone who is hot, will be red.
