Part 2. How can we fix the SD card or memory card not detected on Windows 7/8/10?
Below, we’ll explore some ways to fix the issue based on the possible causes listed above, and we will hopefully get your card reader (and more importantly your SD card) working again.
Try a New USB Port or Card Reader
As scary as it is to have any issues with your files, it is not uncommon for SD cards to stop showing up for any of the reasons listed above. At the top of the list for potential fixes, I suggest you begin troubleshooting by simply testing your SD card and card reader. First, try a different USB port. If the problem persists, then try using another card reader. Hopefully, the issue is with the USB port or the card reader (both of which are still inconvenient), and not the SD card itself. Testing USB ports and alternate card readers is a good way to find out.
If you’ve tried the above fixes and find that your SD card is still not recognized in Windows, then it’s time to move on to some more technical troubleshooting.
Switch the “Write Protected” Slider (If Necessary)
We already mentioned that the “Write Protected” feature may have been activated on the SD card. It’s a little slider that can usually be found on the side of the card (see the image above). If you can’t find the slider but suspect that this feature has been activated, here’s a quick fix:
- Locate the “Disk Drivers” option:
- Access Device management
- Launch the Run Window (Windows key + R)
- Type devmgmt.msc and click the “Ok” button
- Open the ‘Disk Drivers’ option and find your SD card
- Right-click on your card & select “Properties”
- Locate the writing policy option under the “General Tab” or “Policy Tab” and switch the tab off
- Click the “Ok” button
Change or Add a Drive Letter
Assuming this doesn’t help, then you may need to assign a drive letter to the SD card, which you can do by following these steps:
- Locate and select “Disk Management” option (look under the “Start” button)
- Find your SD card and right-click to choose ‘Change Drive Letter and Paths’
- Select the “Change” button & choose a drive letter from the list
- Confirm your selection and exit
- If it turns out that your SD card is missing a drive letter, click on the “Add” button
Run CHKDSK to make the SD Card Detectable
One option you have that often helps those in a similar situation is to run CHKDSK to make the SD card detectable. Just follow these steps:
- Locate and select “Disk Management” option
- Press Windows + R and type cmd. into the box when prompted and then press the
- Type chkdsk D: / f and press “Enter”
Reinstall the Driver for the Card Reader
If you recently updated or upgraded Windows, then you may need to reinstall the driver to resolve the issue and make your card appear on your device again. Here’s how to do that in a few short steps:
- Locate and/or download the card reader driver file. You can typically find the driver file on the website for the brand of the card reader you’re using
- Open and run the driver file
- When the driver file is ready, click “Finish” and insert the SD card reader
- The card reader should now appear under your list of “Devices and Drives”
- Open the card reader
Format the Card
Finally, you may also need to format your card, which I recommend doing only after you’ve retrieved whatever data you don’t want to lose.
Part 3. Using Data Recovery Software
In a worst case scenario, your SD card not showing up could have to do with the card becoming corrupted or damaged. If that is the case, we recommend using specialized software such as Wondershare’s Recoverit Data Recovery (or other similar software) to retrieve deleted or lost data from your corrupted or damaged SD card. This software should simplify the recovery process.
Here’s an example of how to recover and repair data from corrupted SD cards using Wondershare’s Recoverit Data Recovery software:
Make sure your SD card is connected to your computer and select it from the disk list, which you’ll find when you open the software.
The software will automatically scan your SD card and search for data.
When the scan is complete, you can preview and select which files to recover and save to a new device.
These tools often include advanced recovery functions for retrieving all sorts of files, from songs and videos to photos, documents, and emails. The best part about using specialized recovery software is that it’s intuitively designed and often effective. You can try more data recovery software for free in the market when need it.
As you can see, most of the time, the issue can be resolved fairly quickly with just a little bit of troubleshooting. To conclude this article, here are some tips for preventing data loss in the future:
- Only use high quality memory cards from reputable brands
- Only use memory cards in good condition without any physical damage
- Use a memory card wallet to protect your cards
- Consider cameras with dual card slots
