I have a 32GB SD card from Samsung and it no longer works. It is recognized on the cell phone and on several laptops, but it all depends. It can't be formatted, etc. It has bad sectors. The data on the SD card is not important, but can the card be made functional again?
I would say the card is over
Not at all.
The card is broken.
If you still have a guarantee, have it replaced, otherwise it is a case for disposal.
