Mobile telephone TF / SD card (mobile telephone memory card is smaller than the modest fingernail microSD card) Pc can recognize the card, can recognize its capacity and can read the files within the card, but can not create files, nor format! Attempted the following solutions to no avail:

I've attempted a variety of procedures previously couple of days. I'm afraid that the tf card has turn into read-only. I'm not the only 1 encountered. The different techniques on the internet are invalid. There are actually data in the card, images, etc. It really is not simple to ask for warranty. Just get rid of the card reader:
Pretty low-priced card reader. I purchased five of them inside the mobile phone shop at that time. The speed can also be extremely slow. It's affordable and low-priced. I stumbled upon a needle inside the deck that is certainly a sauce purple drop:
Why do you pinch? So I searched the datasheet from the tf card and discovered such a component of content:
It turns out that the
sd card and tf card also possess a spi mode. This spi mode makes use of two fewer pins, that is convenient for communication together with the microcontroller.
