Review on Memory Card Silicon Power microSDXC 64 GB Class 10, UHS-I, R/W 85/15 MB/s, adapter to SD by Janis Endzelins ᠌

After a year of use, it switched to Read-Only mode, and in one session (until the first shutdown) it completely imitates that the recording has been made on it - new files and changes in them are visible. But as soon as I reconnected the card, all changes disappear. I tried all the formatting programs - to no avail, the formatting process goes up to 99% and ends with an error, the files from the card do not disappear after such a "formatting".
