Fix 2. Re-format SD Card

Perhaps there is nothing wrong with the SD card, however, it comes up with the "not formatted" error. The "SD card not formatted" error may cause your phone to be unable to read it, sending the message "SD card unexpectedly removed".

In this case, re-formatting SD card can remove the constantly generated error.

Important
Do not directly format the SD card. Use data recovery software to recover data on it first. After making sure the data is safe, format the SD card.

Stop using your SD card immediately once you lost files on it. Continuing using the card would hugely increase the chance of data overwriting, which makes data unrecoverable.

Step 1: Connect the SD card to PC

Insert the SD card to a card reader, and connect the card reader with your SD card to a healthy computer.

Step 2: Run SD card recovery software and scan the card.

  • Launch EaseUS Data Recovery Wizard on your PC and select your SD card under the External Devices column.
  • Then click Scan to start finding lost data on your SD card now.
Run SD card recovery software.

Step 3: Check found SD card data.

After the scanning process, you can preview and find your lost SD card files from below listed tabs:

  • Deleted Files: List your deleted files there.
  • Drive X: All lost files can be found here.
  • Lost Partition Files: Check first if it's for formatted recovery.
  • Extra Files: Finds files that lost names or paths.

And you can use Filter and Search to quickly find your files.

Find lost SD card files.

Step 4: Restore SD card data.

  • You can check and preview found files by double-clicking each one of them.
  • Then click Recover to save found SD card files to a secure location on your PC or an external storage.
Restore lost SD card files.

Since your phone cannot connect the SD card properly, you should format the SD card using a Windows computer. You can format SD card via Windows File Explorer, Disk Management, CMD and a free disk format utility. All options are free to use. We use the Windows File Explorer as an example.

Step 1: Connect the SD card with a card reader to your PC.

Step 2: In the Windows File Explorer, right-click the removable disk that represents your card, and select "Format."

Step 3: On the popup window, choose FAT under "File System" and Default Allocation Size under "Allocation Size". For other options, leave alone.

Step 4: Click "Start" to format the disk. Safely eject the SD card and insert back to the phone. No error messages are there again. You'll get a blank card for reuse.
