*I am IT professional, not an average consumer.
*Also, the card that s7 doesn't recognize anymore is SDXC, it recognizes non XC (16gb) card. Currently I don't have any other cards to try.
I found the solution after extensive search - downloaded Formatter from sdcard.org/downloads and performed OVERWRTIRE format. The key here was the long format. It's possible the Windows long format (e.g. uncheck quick) would have done it as well but I didn't try it.
Nice investigative work! Thanks for sharing your findings as well!
Hi, the same thing has just happened to me after the July 2018 update my SD card is no longer recognized. Seeing as how they just eats cause people so many problems, I wish there was more straightforward available support than these forms but I appreciate your time in researching this. I am an absolute novice. I was just wondering whether this was a typo on your part...did you mean OVERWRTIRE or OVERWRITE? Do you think the same thing might work for me regarding the latest update? I have tried clearing the cache but I still need to make sure I can access the files on the SD card from another device or computer and due to an accident, I did not make sure to copy the files before the update happened. Hoping they are still there!
P.S. having a horrible time editing this reply as my sentences are not fitting in the screen and when I pull up the keyboard there's almost no space to see what is being typed so sorry if I made any terrible errors.
