    Not sure where to ask this so apologies if not right forum. I'm selling bulk load of old Micro SD cards, I've formatted but want to make sure the photos can't be retrieved using software.

    No mucky ones of the girlfriend I'm afraid lol, just family pics etc.

    Thanks

    Simple answer: Reformat them with the option to write zeroes over the disk. Most home users will then receive a clean card that they cannot see anything else on.

    Complicated answer: My sister works for IBM and basically you can still forensically retrieve data from a disk whether the owner believes they've cleared it or not.....physically destroying it (hammer, fire, nuking from orbit) is the only way to be sure.

    It would be interesting, as a prank to put some data that sounded important or news worthy on some memory cards and just throw a few away, or leave in a few public places, and see if anything comes of it. ;)

    Don't a lot of viruses get deployed in this exact way?

    'Ooh, I wonder what naughtiness is stored within'

    'Give us £million or we won't unlock your data?'

    'DOH!'
