Diagnose and Fix a Malfunctioning SD Card

However, if you don’t have any current or useful backups, you will try best to fix the SD cards. You can take the following 6 effective steps.

1. Insert Your SD Card to the other Devices

If your SD card is entirely unable to being detected out, chances that your SD card is not the actual cause. Perhaps the device which you plug in the SD card to is the culprit. In other words, the device itself can’t recognize and read a SD card. Thus, you can remove your SD card from the current device and connect it to the other devices.

2. Scan and Fix the SD Card via CHKDSK

Like checking the traditional hard drive, you can scan and try to fix your SD card by CHKDSK.

  • Firstly, insert your SD card to a card reader.
  • And then connect it to your computer. If your PC can detect it, move on. Or if not, directly turn to the next tip.
  • Next go to your “Computer” to note the drive letter assigned to the SD card.
  • Later open the “Start Menu” and search “cmd” and press “Enter”.
  • In the Command Prompt window, you can type “CHKDSK drive letter:/f” and hit “Enter” key, for instance, “CHKDSK E:/f”.

3. Assign a Drive Letter to the SD Card Manually

In the above step, maybe you will find that the SD card cannot display or you will get an error message, mentioning that please insert the disk into drive. It means that your operating system is not reading the SD card. In most cases, it is because that your system hasn’t assigned a drive letter to it. Therefore, you should assign a drive letter to it manually by changing your operating system settings.

4. Re-install the Driver

Moreover, this issue can stem from your computer driver’s faults. Hence, you can reinstall your computer driver to have a try.

  • First, open “Start Menu”
  • Then, right click on “Computer” and select “Manage” from the context menu.
  • Next click on the “Device Manager” on the left side.

  • Subsequently, from the right clicking menu, select “Uninstall”.
  • Now remove the SD card and restart your PC.
  • Lastly, insert the card again to check if it can be detected.

5. Disable Write Protected Mode

If actually you are permitted to read your data in the SD card but you can’t save your modifications on the data, it is possible that the SD card is in write protected mode. In this case, you can simply unlock the switch or change specific settings to disable the mode.
