And additionnaly, isn’t there a way to exploit this so we can store more stuff on PCs?

Edit: can’t thank you all individually but thanks to everyone, I learnt something today, appreciate all of your replies!

    Follow up question: If I reformat and write my drive with 0s, how reliable are the mechanisms to recover previously stored data on:

    • An hdd
    • A ssd

    Asking as a hypothetical for a hypothetical friend.

      If you actually fill the drive with zeroes, the chances of anyone getting anything back are somewhere between fuck and all.

      Old MFM drives (tech likely as old as your parents) had a theoretical exploit for recovering erased data.

      With modern tech, that loophole was firmly closed; even state-level actors would be shit outta luck.

      dban is kind of the standard for wiping data, which iirc is 3 cycles of overwriting everything with 1s, then 0s.
