    Last night my phone suddenly reported that my sd card (sandisk extreme Pro 128gb micro sd) had a problem (i think to write to it) so it has made it read only. After restarting the sd card wasnt detected any longer. When connecting it to my Mac or asked if i wanted to format it. When looking at it in an app or seemed it was so as exfat format(is that normal for Android?). I used 2 days recovery apps that found about 1\3rd of the data.

    1. What has actually happened to the card and was it the card or my android (Samsung galaxy s10+)?

    2. What is the best way to un delete the card to recover correctly from? If not possible what is the best way to recover as much data as possible? (Should i use Windows or can i use Mac for the same effectiveness?)

    3. should i reformat the card after recovering the data or just bin it? I'd there a way to assess if it is trustworthy still?

  2. SD cards die, typically just like this. If you're lucky they stop writing before they stop reading so you can recover the data before throwing them away. In this case you got some of the data back, it is possible by trying some different recovery programs you might be able to get more.
    Just get as much as you can off of it, don't bother to reformat or try to use it any further as it's most certainly shot. Get a new one.

    Once they fail it's time to pitch them in the bin. They might give you some additional mileage with a format but for the replacement price... it's a great time to move on. Good luck in recovering what you can.

    thanks guys. is there an app you recommend for recovery?
    is there also an android app you know of that can regularly run a test on an sd card and notify you if the card is beginning to break?
