Is it possible to make a memory card work?

Question

Memory cards

Hello everyone! I bought a microsd on Ali, I worked for a month and that's it. Now you insert only up to 20% and what to do?
Tried in fotik Canon writes your card is blocked. Can I do something with it or throw it away?

Answer 1

After the purchase, did you test the card for compliance with the declared capacity? Those. before she allowed herself to write as many GB as indicated?
And then on Aliexpress it is quite possible to buy a variety of bullshit under the guise of a normal drive.
In general, you can try to test the microSD with R.tester to understand what's wrong with it, but it's more of a curiosity if you have time.
If the USB percent is known, then the Tester will determine the type and size of the NAND.
In any case, I would advise not to use it for anything important, and the ideal option would be a dispute on Aliexpress with the microSD seller and a refund, or a new memory card.
