How to Fix SD Card Deleting Files by Itself 

After recovering missing files from SD cards, you can try the following methods to fix SD card deleting files by itself without any worry. 

Fix 1. Try Something Simple and Effective

Here are some simple methods to help fix the "SD card deleting files by itself" error. 

Step 1. Unplug the SD card (if you haven’t ejected it) properly by checking “Safe to Remove Hardware”.

Step 2. Clean the SD card and its interface with a tidy and dry towel or tissue.

Step 3. Replug the SD card carefully.

This may be helpful if this error occurs on Android. If not, you can still try antivirus software to scan and kill viruses on the SD card or your machine.

Fix 2. Unhide SD Card Files Disappeared

Viruses might hide your files. Try to unhide disappeared files from SD card and check if there are any missing files.

Step 1. Connect your SD card to your computer and open it. 

Step 2. In File Explorer, click View > Options > View > Show hidden files, folders, and drives.

Step 3. Check if there are lost files back or shown.

Fix 3. Use the CHKDSK Command

The CHKDSK command in CMD can help you check and fix logical/physical file system errors. It can mark the bad sectors as unused as well. 

Step 1. Connect your SD card to your device. Type cmd in the Start menu and select Run as administrator.

Step 2. Input chkdsk x: /f /r and press Enter. It will try to look for bad sectors and fix possible errors on your drive. Please replace x with the exact drive letter of the SD card.

⚠️Note: The /r parameter contains the function of the recovery command in CMD, thus it can recover readable info from SD card, but the effectiveness won’t be that satisfying.

Fix 4. Delete Faulty Apps or Nomedia Files

Sometimes, the "SD card deleting files by itself" error is caused by malicious and corrupted apps.

• If there are any, you need to uninstall the faulty apps to fix this error.

The nomedia file tells the media player that there is no multimedia data in this folder and no need to scan it. It's hidden and invisible to most built-in file explorers. You need to use a third-party one, such as ES File Explorer. 

Step 1. Open the ES File Explorer. Then, click the blue icon in the upper left corner.

Step 2. Go to the Tools option, and click Show hidden files. If there is a nomedia file, select it and press Delete.

If the error still exists, you need to format it to restore its health state. But this operation will delete all data on the SD card. Please Back up SD card data before formatting using a reliable backup software.

Then, you can format the SD card without worrying about data loss.

Step 1. Right-click the Start icon and select Disk Management.
