Reasons of SD Card Shows up “Secure Digital Storage Device” in Windows?
It shows up “Secure Digital Storage Device” as we insert the SD card into the PC. What does it means? Such problem should be discussed in two situations.
Situation 1. Can be Read by PC
If your SD card can be read by the PC, “Secure Digital Storage Device” maybe just the drive name defined by Windows. After all, this is the full name of SD card.
Situation 2. Cannot be Read by PC
If your SD card cannot be read by the PC, you can try the suggestions below:
1. Change another card reader. It could be incompatible with the card reader.
2. Change another port or slot. Maybe there is something wrong with the USB port or the slot.
3. Reinsert the SD card or use an eraser to gently clean the contacts. The dirt on the SD card will cause higher electronic resistance, which will prevent connection.
4. Press the card a little harder or wrap it around a piece of paper. The contacts may be not elastic anymore, so it cannot connect to the port or the slot rightly.
5. Change a new SD card if the hardware is faulty.
6. Possibly, the SD card has been encrypted and enabled write-protection.
You can follow these methods to remove write-protection:
(1) Unlock SD card with the physical switch
Alongside the SD card, some manufacturers will add a switch. If it is locked, the file in the card cannot be modified. You can check and keep it unlocked if your SD card has such switch. Then you can insert the SD card again.
However, if your SD card doesn’t have such lock, please refer to the following methods.
(2) Use registry to remove write-protection
① Connect the SD card to the computer.
② Press the keys [Win + R] to open the Run box.
③ Type [regedit] and hit Enter to run Registry Editor.
④ Navigate to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control]. Then check the key [StorageDevicePolicies] in Control. Then at the right side, double-click [WriteProtect] to change the value to “0”.
⑤ If you can’t find the item [StorageDevicePolicies], right-click at [Control] and add a new key named as [StorageDevicePolicies]. Then, right-click at the blank area to add [DWORD (32-bit) Value] or [QWORD (64-bit) Value] named as [WriteProtect]. The bit is based on your PC system.
⑥ Then double-click [WriteProtect] and change the value to 0. Reinsert the SD card to check.
As all these methods have been carried out, the SD card still cannot be read. You can try to format the card. It is noted that the data should be backed up beforehand. If the data is lost unluckily, the third-party software may help you recover them.
① Right-click at the SD card to select [Format].
② In the pop-up window, select the file system and click [Start].
③ Then the system will notify you all data will be erased. Click [OK] to confirm.
④ Await formatting.
If you lost important data in the SD card, you can follow these steps to recover them quickly.
