My Lenovo Moto G4 (Android 6.0.1) died recently. I sent it for repairs, without the SD card I used for internal storage (I don't remember asking for it to be encrypted). The phone just came back, with a complete factory reset.

Inserting my SD card, I was hoping to at least get back the files on it, but I get the "Unsupported SanDisk SD card" message.

When I try to open the SD card with my computer, Windows fails and tells me the card must be formatted.

  • Is there a specific procedure to restore files from a SD card formatted for Androids internal storage?
  • Is it otherwise possible that my SD card was corrupted when the smartphone died?
  • Any idea how to get my files?

    Sorry, but you have to say goodbye to the data stored on it. If you used it as "internal storage", it was encrypted – and the encryption key stored on the device, where it is gone from due to the factory-reset. For details, please see our adoptable-storage tag-wiki.

    That's one big contra on adoptable-storage. I strongly recommend reading at least the above mentioned tag-wiki before deciding on using it. Too late for you, I know. I blame "marketing" for that, which only underlines the pros and (at least in this case) completely forgets to mention the cons and the pitfalls.

Try getting your files off the SD card using linux. Depending on what format the card was formatted with Windows wont r/w to it without first formatting it.

  • Won't work if the card was used as internal storage. See my comment on the question itself: the computer won't be able to read the partition, as it's encrypted. So without the encryption key, not even Linux can get to the files stored on it.
