I'm having troubles with a 32 Go Transcend micro SD card (on Samsung Galaxy A5 2016, Android 7.0). When my phone starts, it displays the following notification:
Unsupported SD card This device doesn't support this SD card. Tap to set up in a supported format.
If I click the notification, it asks me to format the SD card, which I obviously don't want to do.
I tried many things, unsuccessfully:
- shut down the phone, remove the card, put it back and restart the phone
- connect the phone to a computer with a USB cable -> doesn't show the SD card, only the phone internal storage
- remove the card and connect it to a computer using a micro-SD/SD adapter (on two computers, one running Windows 7 and the other running Ubuntu 16.04) -> doesn't show the SD card. I tried with another micro-SD card on both computers to check that the adapter and the SD card reader are OK and it worked.
- wipe the connectors
So I have no way to access my data.
I don't know if it's relevant, I was running NewPipe when that happened. I just watched a video, and then I couldn't play another one. Then I tried to Samsung Music. I could see the titles but the tracks won't play. So I restarted my phone and saw the error message for the first time.
I'm now running out of ideas...
