forat meaning everything will be delted ? just asking to make sureHey, you should format the sd card before doing the test as Fat32 32kb cluster size, then run the test with the write & read option.
- If it passes the test, then your sd card is fine, and you should format it (again) as Fat32 32kb cluster size (64kb if it's a +64GB card), and follow the guide above.
- if it doesn't pass the test, then it's fake or defective and you shouldn't use it. Get a new replacement sd card and test it out just the same when you get it.
