problem writing to card "write protected disk"

[beropolis]

Hello
I am the owner of a canon eos 4000d. after reading the article on tamat ML, I wanted to try it out. Unfortunately, on two different carats when copying from a computer or formatting, the message "write-protected disk" appears. I checked the mechanical security of the card, tried to format from .cmd and change the registry. Unfortunately with poor results.
I will add that the cards were used on my camera and shared the pictures correctly, you can copy and make the format from the camera, but nothing can be copied to the card from the computer.
