so in second and third tests in h2testw they should still be an error and bad sectors in results?just reformatting the device will not mark bad sectors. You will need to run chkdsk, this will mark them as bad sectors and reallocate reseve sectors from a hidden spare area. Then bad sectors will not show up again. Chrystal Disk will show a value of the amount of used reseve sectors, if a high amount would be probably used will say the card is dying.

ofc it is not know for SD cards but they sell some stuff and to be honest I go for it because of price and I was curious : DI still would be more cautious since it did throw the media is likely to be defective , also Silicon Power isn't popular for micro SD.
