Why Is SD Card Not Showing Up?

Are you wondering why your SD card is not detected properly? There are several possible reasons:

  • ⚡ Poor connection: SD cards communicate with compatible devices using a series of metal pads, with each pad serving a different purpose. Over time, these pads can become worn out and cause various connection issues.
  • 🔨 Mechanical damage: Even though SD cards can survive a lot despite their somewhat flimsy plastic construction, they are definitely not immune to mechanical damage. Companies like SanDisk, Samsung, Sony, PNY, and Manfrotto sell waterproof SD cards, but most standard SD cards don’t like water just as much as they don’t like being dropped on the ground, stepped on, or left in a humid environment.
  • ❓ Logical corruption: Because the data stored on a single SD card is typically accessed from several different devices and operating systems, logical corruption of individual files or even the entire file system is a fairly common occurrence that can sometimes be solved using specialized software.
  • 💻 SD card reader not working: Just because you can’t access files stored on your SD card doesn’t mean the SD card itself is to blame. It’s also possible that the SD card reader is not working as it should.
  • ⛔ Unsupported file system: There are several file systems commonly used in SD cards and other memory cards, including FAT16, FAT32, and exFAT. However, you can format an SD card to any file system you want. Just make sure that all your devices and operating systems support it.

You should also keep in mind that full-size SD cards are equipped with a lock switch on the left side that makes it possible to lock all stored files and prevent them from being deleted or modified. Whenever you can access your SD card but are unable to format it or otherwise delete/modify its content, make sure the switch is in the “OFF” position.

How to Fix the “SD Card Not Showing up” Issue?

There are many possible fixes for the “SD Card Not Showing up” issue, and you need to pick the one that best fits your specific situation. Take a look at the table below for a quick overview of available recovery methods:

How to Fix SD Card Not Detected, Not Showing, or Not Reading Error on PC

Most Windows 10, 8.1, 8, 7, and XP users have experience with an SD card not showing up or displaying an error message. By methodically trying the five fixes described below, you should be able to solve just about any SD card issue you may encounter.

Fix 1: Reinstall the SD card reader driver

The fact is that most SD card issues are not caused by SD cards—they are caused by SD card readers and their drivers. That’s why you need to first verify that your SD card reader is working correctly by inserting another SD card into it. If you discover that it isn’t, reinstall its drivers:

  1. Press Windows + X.
  2. Select Device Manager.
  3. Select your SD card reader under Disk drives.
  4. Open the Action menu and choose Update card not reading

Fix 2: Assign a new drive letter to the SD card

You can’t access an SD card on a Windows PC unless the SD card has been assigned a unique drive letter. Although Windows is supposed to assign drive letters to storage devices automatically, things don’t always go according to plan. Even if when they do, simply changing the drive letter to a different one is sometimes enough for Windows to recognize an SD card. To manually assign a new drive letter to your SD card:

  1. Press Windows + X.
  2. Select Disk Management.
  3. Right-click your SD card reader and select the Change Drive Letter and Paths card reader not working
  4. Pick a new drive letter and confirm.

Fix 3: Use CHKDSK to repair SD card corruption

CHKDSK is a useful command-line tool that can automatically repair many file system errors to make a corrupted SD card usable again. The tool may seem somewhat intimidating, but it actually takes just one simple command to repair an SD card with it:

  1. Press Windows + X.
  2. Select Windows PowerShell (Admin).
  3. Enter the following command (make sure to replace X with the letter assigned to your SD card) and press Enter: chkdsk X: /Rsd card not recognized
  4. Wait for CHKDSK to finish. The process may take several hours, depending on the size and speed of your SD card.

The /R parameter tells CHKDSK to checks the entire SD card for bad sectors and repair them if possible.  

Fix 4: Create a partition on the SD card

Brand-new SD cards are sometimes not recognized properly when they don’t have a working partition. If you weren’t given the option to format the SD card after connecting it to your PC, you need to create a partition manually:

  1. Press Windows + X.
  2. Select Disk Management.
  3. Right-click the unallocated SD card space and select the New Simple Volume card not detected
  4. Click Next three times and choose to format the new volume. You can keep the “Perform a quick format” option checked.
  5. Click Next and then Finish.

Fix 5: Recover data from the SD card

If you’re still seeing SD card errors despite trying multiple different fixes, then it’s possible that the SD card is failing. In that case, you should stop using it as soon as possible and get a new one instead. But before you do that, you may want to recover your data using a data recovery application like Disk Drill:

  1. Download and install Disk Drill for Windows or Mac.
    Disk Drill
    Data recovery for free
    Your Companion for Deleted Files Recovery
  2. Connect the SD card to your computer and launch Disk Drill.
  3. Select the SD card and click Search for lost data.Searching for data with Disk Drill.
  4. Check the files you want to recover.
  5. Click the Recover button at the bottom.Marking the files for recovery.
  6. Specify the recovery destination and click OK to begin the recovery of your files.Completing Disk Drill recovery.

Fix 6: Show SD card files hidden by a virus

Malware, after infecting your device, is capable of hiding your files so they don’t show in File Explorer. This could lead to you thinking that the files were wiped when they’ve actually been there the whole time, just out of view. Follow these instructions to show any hidden files on your SD card:

  1. Right-click Start and select Windows PowerShell (Admin).Opening an elevated PowerShell console.
  2. Type cd E:. Replace E: with the drive letter of your SD card. Press Enter.Executing the cd command.
  3. Type attrib -h -r -s /s /d E:\*.*. Again, replace E: with your SD card drive letter. Press Enter.Executing the attrib command.

After running this command, any hidden files on the SD card will now be visible. If your files are visible, proceed to take them off the drive and back them up.

Repair SD Card Not Detected on Android Phone

One great thing about Android phones and tablets is their ubiquitous support for SD cards. But with so many different manufacturers selling so many different devices, issues with SD cards not being detected are fairly common. The following solutions can help.

Fix 1: Unmount and remount the SD card

This unlikely solution is surprisingly effective when it comes to solving issues with SD cards not being detected correctly by Android devices. Here’s what you need to do:

  1. Open the Settings app on your Android device.
  2. Go to Storage > SD card.
  3. Tap the Eject icon next to your SD card (older Android devices will have the “Unmount” option instead).sd card not reading on phone
  4. Restart your Android device.
  5. Go back to Storage > SD card and tap mount.

Fix 2: Clean the SD card slot

Your Android device most likely spends a lot of time in your front pocket, purse, or backpack. There, it’s exposed to everything from regular pocket grime to crushed potato chips, and who knows what else. Some of this filth can find a way inside the SD card slot and cause your memory card to lose connection from time to time.

We recommend you clean the SD card slot using a can of compressed air. To achieve the optimum force out of a can of compressed air, it’s recommended to spray short blasts in quick succession.

Fix 3: Format the SD card in your phone

This fix will work only if your Android phone can recognize that an SD card has been inserted. It doesn’t, however, need to be able to access its content. If your device can’t detect the SD card at all, then you can try formatting it on your computer just like you would any other storage device.

Because it would be beyond the scope of this article to provide step-by-step instructions for multiple brands of Android devices, we decided to focus only on Samsung, which has the biggest market share. That said, the steps should be more or less the same on other phones.

To format an SD card on a Samsung phone:

  1. Go to Settings > Device Care.
  2. Select Storage.
  3. Tap on Advanced.
  4. Select SD Card under Portable storage.
  5. Tap on Format.
  6. Select Format SD card not detected android

Fix 4: Perform a factory reset

There’s a chance that the issue with your SD card not being detected is caused by a software error. If you’re okay with completely erasing your personal information and data to make your phone a clean slate, then you can perform a factory reset. Here’s how to do so on a Samsung device:

  1. Open the Settings app.
  2. Search for and select Factory data reset.
  3. Tap Factory data reset again
  4. Tap Reset.
  5. Enter your credentials.
  6. Tap Delete card not working

Most other manufacturers have a similar factory reset process.

The main thing to keep in mind when performing a factory reset is the fact that all your personal information and data will be erased. When that happens, undeleting them will be possible only using specialized data recovery software like Disk Drill, which can access your rooted Android device’s storage and recover deleted data directly from the internal memory or SD card.

Fix 5: Repair hardware issues

While software issues can almost always be fixed at home, the same can’t, unfortunately, be said about hardware issues, such as when either the SD card or the phone itself is damaged. In such situations, it’s best to send the entire device, and the SD card with it, to a professional data recovery center.

Professional data recovery centers are equipped to recover data even from mechanically damaged SD cards and flash memory chips, such as those found inside modern Android smartphones, and they typically charge only for recovered data.

Fixed: Nintendo 3DS Could Not Detect an SD Card

Is your Nintendo 3DS having trouble detecting your SD card? Then you can try the fixes below to solve the problem.

Note: Do not remove or insert SD Cards while the system is on or while the adapter is still in the system.

Fix 1: Check that the card is compatible

Both the new and original Nintendo 3DS and Nintendo 3DS XL systems are compatible with SD cards up to 2 GB in size, and SDHC cards of 4 GB and larger up to 32 GB in size. SDXC and microSDXC cards are not considered compatible and should therefore be avoided.

If your SD card isn’t compatible with your Nintendo 3DS, then you need to purchase a new one. We recommend you get one from a reputable memory card manufacturer to avoid reliability and performance issues.

Fix 2: Ensure the SD card is unlocked and inserted correctly

The Nintendo 3DS won’t accept your SD card unless it’s unlocked and inserted correctly. To check that it is:

  1. Turn off your Nintendo 3DS.
  2. Remove the SD card.
  3. Slide the lock on the left side up so that the lock is in the top position.
  4. Carefully reinsert the SD card into your 3DS (the new 3DS uses a microS card).sd card nintendo
  5. Turn your 3DS back on.

Fix 3: Use the Nintendo 3DS Download Repair Tool

If you’re experiencing issues with your SD card only with a specific downloadable game or application, then Nintendo recommends you use the Nintendo 3DS Download Software Repair Tool, which can be downloaded directly from Nintendo eShop. This tool can check downloaded data for errors and attempt a repair.

Fix 4: Format the SD card

The Nintendo 3DS and Nintendo 3DS XL only accept SD cards formatted to the FAT32 file system. If your SD card uses a different file system, then you need to reformat it.

Nintendo recommends using the SD Memory Card Formatter developed by the SD Association, an American non-profit organization that sets memory card standards. This tool is compatible with Windows 7 and newer and Mac OS X 10.7 Lion and newer. Here’s how to use it:

  1. Download and launch the SD Memory Card Formatter.
  2. Choose your SD card.
  3. Select Overwrite format.
  4. Click the Format card formatter

Should you accidentally format the wrong SD card, you can use Disk Drill or a similar data recovery application to recover your data.

How to Fix “Camera Won’t Recognize SD Card”

Is your camera (Canon, Nikon, Sony, Fujifilm, Olympus, Panasonic, Pentax, Leica) camera displaying the “camera won’t recognize SD card” error or a similar message? Then you need to go through the fixes listed below to troubleshoot the problem.

Fix 1: Check if the SD card is supported by the camera

Not all SD cards are supported by all digital cameras. Older cameras support only SD and SDHC cards, so you need to verify that the type and capacity of the memory card are supported by your camera:

  • SD: Up to 2 GB
  • SDHC: 2 GB to 32 GB
  • SDXC: 32 GB to 2 TB
  • SDUC: 2 TB to 128 TB

If your memory card isn’t supported by your camera, there’s nothing you can do to make the two work together.

Fix 2: Check if the SD card is inserted correctly

Before you try more technical fixes, you should check if the SD card is not inserted in the wrong direction or at a slant. While it shouldn’t be possible to insert SD cards incorrectly, even a mountain can be moved with enough determination and force.  

sd card camera insert correctly

To correctly insert the SD card, open the memory card cover (if present) and slide the card in by pushing the center portion of the bottom edge until it clicks into place at the back of the slot.

Fix 3: Clean the pads on the SD card

Over time, the pads on your SD card may become dirty and lose the ability to establish a reliable connection. You can easily clean them using a cotton swab and isopropyl alcohol. If you don’t have isopropyl alcohol at home, then regular rubbing alcohol or even just a dry piece of cloth will do fine. Once clean, simply reinsert the SD card and test if the error is still present.

Fix 4: Move the lock to the “off” position

The “camera won’t recognize SD card” error message is rarely displayed because the lock present on a full-size SD card is in the “on” position, but you should still move it to the “off” position just to be safe. Simply take out the SD card and slide the lock up.

unlock sd card

If the lock is missing, then you need to fix it. We recommend this Instructables tutorial because it uses only one thin piece of clear cellophane tape.

Fix 5: Reformat the SD card on your computer

In some cases, the “camera won’t recognize SD card” error is displayed because the file system is unsupported by the camera. In such cases, you need to reformat the SD card on your computer.

But before you do that, consider using a data recovery application like Disk Drill to recover all important files that may still be present on the SD card.  

Have you successfully recovered your files using Disk Drill? Great! Here’s how you can reformat your SD card on a Windows or Mac computer:

Windows Mac
1. Insert the SD card into your memory card reader.
2. Open File Explorer.
3. Go to This PC.
4. Right-click your SD card.
5. Select the Format option.
6. Choose a compatible file system and click Start.
1. Insert the SD card into your memory card reader.
2. Open Disk Utility app.
3. Select your SD card from the list of devices on the left.
4. Click the Erase button.
5. Choose a compatible file system and click Erase.

Tips to Protect Your Memory Cards

memory cards

Because issues with files on SD cards not showing up as they should are fairly common, you should actively protect your data by following the tips below:

  1. Protect your SD card from mechanical damage: It goes without saying that you need to do everything you can to protect your SD card from mechanical damage by handling it carefully and storing it inside a protective case when not in use.
  2. Turn off your device first: To avoid issues with file corruption, make sure to always first turn off your device before removing the SD card.
  3. Format your SD card in your device: Whenever possible, format your SD card directly in the device the SD card is intended for. That way, the device will use the most appropriate settings to avoid corruption and ensure maximum performance.
  4. Use multiple SD cards: Just like all other storage devices, SD cards can fail unexpectedly. That’s why it’s always a good idea to avoid putting all your eggs in one basket by using multiple SD cards.
  5. Stop using the corrupted SD card ASAP: By ignoring corruption, you’re guaranteed to make the problem worse and lose even more data. Instead of hoping for the problem to magically fix itself, stop using the corrupted SD card as soon as possible, and follow the instructions in this article to fix the problem.
  6. Safely eject your SD card from the computer: Both Windows and Mac give you the option to safely eject your SD card when you’re done using it, so take advantage of it because it’s there for a reason: to prevent data loss.
  7. Avoid no-name SD cards: The top manufacturers of SD cards include SanDisk, Kingston Technology, Lexar, ADATA Technology, Transcend Information, Samsung Group, Sony, and Toshiba. These companies produce reliable SD cards that don’t cost much more than no-name SD cards, so we highly recommend you pay extra for better quality.
  8. Don’t let your SD card fill up: All flash-based storage devices, including memory cards, USB flash drives, and eMMC, stop being able to deliver the best performance possible when allowed to reach 100% of their capacity.
  9. Don’t use the same SD card on multiple devices: Even though modern operating systems and devices can understand one another, they all have their own distinct “dialects,” which is why using the same SD card on multiple devices can create all sorts of issues.
  10. Keep your batteries charged: The last thing you want is for your camera to die in the middle of saving an important video on the SD card, so keep your batteries charged and stop using your device when you have only 10% or so of power left.

With these 10 tips, you should be able to avoid most issues with SD cards not reading correctly. But even if you do encounter one of the issues described in this article, you can just follow our instructions and fix it in no time.
