Actually, I revived a card that I couldn't write to with that program. Otherwise I wouldn't have mentioned it.
I'm not sure why you would think I'm unaware of dd and variants. But for the particular card, the official sd software, though version 3, had some extra foo.

You may be able to revive the card with the official SD card formatter.

Unfortunately, no linux version.
Thank goodness for that! No vendor- or industry-interest-group-supplied advertising. Phew. The Linux version of said program is called dd. You use it to copy from /dev/zero to /dev/sdX, with sdX being the card's device name. This erases all memory on the card (ignoring the "protected area", which above mentioned squishware does likewise). After that, use mkfs with parameters of your choice. (Yes there is potential for bad choices to affect performance. The power to not do so is yours to use.) There are ways to use dd for rudimentory testing of flash card memory. In any case, faulty flash memory doesn't need to be revived, it needs to be stored in the refuse recepticles provided for such purposes. For boards like RPi and Cubie I personally wouldn't choose the cheapest and c**piest sd cards. TBH I can't think of any useful purpose for such cards.
