How to do SD card integrity test on Windows 11 and 10?
There are 3 easy and practical methods for checking SD card health on Windows 11 and 10. You can follow them and see if your SD card is still integrity.
1. Check for symptoms of a corrupted SD card
How to check if SD card is corrupted? See the symptoms of the corrupted SD card may be the most direct way. Signs of a corrupted SD card include:
2. Card readers and computers can't open the card as a readable folder.
3. Files on the card appear distorted or show errors.
4. You can see the card as a folder, but not all files are visible.
When you see these signs, stop using the SD card to avoid further damage and data loss. You can immediately use a professional data recovery tool to restore any important data at this time.
2. Run CMD to test SD card integrity
A lot of PC experts say that the Command Prompt that comes with Windows is the best way to check a storage device. If you type a few commands into the Command Prompt, it will check an SD card to see if it has any errors or bad sectors. However, since it can lead to errors, it is recommended that computer novices choose a safer method.
Step 1. Press “win + r” to open run box, input “cmd” on it and press Enter.
Step 2. When the Command Prompt is launched, type “CHKDSK [drive letter]: /f /r /x”, and press Enter to start the checking process.
The progress will be demonstrated on the Command Prompt dialogue, and you can view how many file is examining and bad files have been found and other results.
If you still think your SD card is not working, you can check if the MBR is corrupted. You can also check and fix it with the Command Prompt.
✍Note: MBR (master boot record) is a type of boot sector at the beginning of an SD card. It contains the important information of the SD card, including how the data is stored and retrieved. Repairing corrupted MBR can solve some unexpected problem on a storage medium.
Step 1. Connect your SD card to your computer, and open Command Prompt.
Step 2. Input following commands on Command Prompt:
● bootrec /scanos● boot rec /fixmbr● bootrec /fix boot● bootrec /rebuildbcd
3. Test SD card integrity via Check Disk Tool

Step 1. Open File Explorer
Step 2. Find out the drive on the write-protected SD card and right-click it.
Step 3. In the drop-down menu, choose “Properties”. Then, click “Check Now”.
