Indeed. And as I said already, unless the card is pathologically underused, “what blocks of flash have been written to” eventually becomes “all of them”. So you have two options: - Either when a card has been written in (almost) full once it stops being able to do wear-levelling and quickly dies. - Or the suggestion that this is how wear-leveling works was wrong and based on insufficient reasoning about the mechanisms involved. > So, if like me, you have a 64GB card, with just a 4GB partition Pathologically underused. A more typical use of a card would be “damn, my camera/phone/recorder tells me the card is full, I need to copy a few things to the cloud”. Regards, -- Nicolas George
