I bought a 1tb green model SSD last year, but now this error appeared when performing a diagnosis, the “retired block count” error. I would like to know about this error, how to fix it, if it affects the files that are in it.

Google “retired block count” it’s not good.

Bad blocks are retired after the OS writes new data to them, or they could be pre-emptively retired if the SSD is able to read them after they have been marked as unreliable. In short, there is no data loss. However, I would backup your data and consider replacing the drive if the numbers are large, or if they are growing regularly.

Thanks for the clarification, I will monitor, if the number increases, I will make the exchange. I found it strange because I have other SSDs with much more time of use and that did not present such a problem.
