Technology can oftentimes be an enigma. One moment your SD card is working completely fine, the next you’re scratching your head trying to figure out why none of your devices are reading it. Why does this happen?
Why Is My SD Card Not Working or Unreadable?
This problem can occur for a number of reasons, many of them having no relation to each other. Sometimes it can be as simple as the port on your device being blocked by lint or dust. Regardless, here are the most common causes for your SD card not showing up:
❌ Incompatible file system
😢 Corruption
💥 Hardware problem
🔧 Outdated or corrupted drivers
No matter which of the above problems resulted in your SD card not working, let’s move on to recovering data from your SD card before we look at solutions to ensure your data is safe and sound.
How to Recover Data From SD Card That Is Not Showing Up
You might be wondering, how is it possible to recover data if the SD card is not reading? Well, through the use of data recovery software. Data recovery software has the ability to read your SD card, even when it’s not visible in File Explorer. Basically, as long as it’s visible in Device Manager, you have a chance of recovering your data.
For this process, we’re going to use Disk Drill, a widely trusted data recovery tool that specializes in the recovery of data in situations like this. It uses advanced algorithms that can access your SD card and pull your data from it before it gets to a point where it’s no longer usable.
Follow these instructions to recover data from an SD card that’s not recognized:
- Download and install Disk Drill.
- Select your SD card from the list of devices in Disk Drill. Next, click Search for lost data.
- Click Review found items upon completion of the scan.
- Check each file you want to recover. Make use of the preview window by double-clicking any file in the view to see the contents of the file. When you’re ready, click Recover.
- Choose an output location that doesn’t reside on the SD card. Click OK.
How to Fix SD Card Not Detected, Not Showing, or Not Reading Error
The issue with your SD card not appearing can happen for many reasons across many devices. Therefore, we’ve broken down the next section by device so you can find a solution for your particular problem.
General Methods
First, we’ll look at some preliminary checks you should do before moving on to bigger fixes. Performing these first can potentially save you hours of needless troubleshooting.
General Method #1: Clean the SD Card and Port
Before your device can read your SD card, it needs to make physical contact. If the SD card or port you’re connecting to contains dust, lint, or other foreign objects, it could be preventing the SD card from making contact with your device.
Clean the contacts on your SD card using a lint-free cloth. Do the same for the SD card port by gently removing any obstructive substances using an earbud. Consider using isopropyl alcohol for more persistent substances that have built up over time (but be sure not to use too much and allow your device to dry before using again).
General Method #2: Disable Write Protection
On the left side of your SD card, you may find a small switch that is labeled “lock”. When this switch is slid up, it means the card is unlocked. When it’s slid down, it means it’s write-locked. This write lock, when enabled, ensures that none of the SD card’s contents are modified. It also prevents new data from being saved.
If you’re having issues with your SD card, make sure it’s in the unlocked position before using it.
Methods for Windows 10/11
Solutions for fixing an unreadable SD card on a Windows laptop or PC are well-documented. Here are a few of the most effective solutions.
Windows Method #1: Update or Reinstall the Drivers
Drivers are what allow for communication between your device and your Windows 10 or Windows 11 computer. Without drivers, your computer will be unable to detect any hardware device that you connect to your computer.
These steps will show you how to update your SD card and SD card reader drivers, as well as reinstall them if they have become corrupted:
- Right-click Start, then select Device Manager.
- Expand the Disk drives dropdown. Right-click your SD card, then select Properties. Bear in mind that your SD card may be named something else. Look for the brand of your SD card, for instance, SanDisk or Lexar.
- Click Driver, then click Update Driver.
- Click Search automatically for drivers. If any updated drivers are found, proceed to install them. Alternatively, install locally stored drivers by clicking Browse my computer for drivers instead. If not, click Close and proceed to the next step.
- Click Uninstall Device.
- Click Uninstall.
Once the driver is uninstalled, safely remove the SD card, then reconnect it to force the drivers to reinstall.
Windows Method #2: Assign a Drive Letter
Believe it or not, assigning a drive letter (or changing the existing one) can potentially fix the error of your SD card not showing up. This is because Windows has always relied on assigning drive letters to attached storage devices.
These steps will guide you through assigning a drive letter to your SD card, or changing the existing one:
- Right-click Start and select Disk Management.
- Right-click the volume of your SD card, then select Change Drive Letter and Paths.
- Click Add. If there is already one there, select it then click Change.
- Select a drive letter from the dropdown, then click OK.
Windows Method #3: Fix Using CheckDisk
CheckDisk is a command included with Windows intended to find and resolve problems relating to the file system of attached storage devices. Have you ever noticed the error checking option when viewing the properties of a drive? That function is basically CheckDisk with a graphical user interface.
These instructions will guide you through running CheckDisk on the SD card to repair any problems that may be present with the filesystem:
- Right-click Start and select Windows PowerShell (Admin). If prompted by UAC, click Yes.
- Type chkdsk D: /f /r. Replace D: with your SD card’s drive letter. Press Enter.
Windows Method #5: Format the SD Card
Formatting your SD card is always a great solution if your computer picks up the SD card in Device Manager, but is unable to access it. This probably won’t work if your computer won’t read the SD card. The process involves removing the existing file system and either replacing it with a new one or simply refreshing the existing one.
- Right-click Start and select Disk Management.
- Right-click the volume of your SD card and select Format.
- Provide a label for your SD card and make sure the file system is FAT32 (our screenshots show NTFS for demonstration purposes). Ensure Perform a quick format is selected, then click OK.
- Click OK again.
Methods for macOS
For Mac users, a lot of solutions are similar in nature to that found on Windows. Let’s look at how you can make an SD card readable again using macOS.
macOS Method #1: Check Your Finder Preferences
It may be that your SD card is recognized, but hidden. This is easily fixed. To do so, you just need to enable visibility in Finder. Follow these steps to do so:
- Click Finder, then select Finder > Preferences.
- Click Sidebar, then make sure your SD card is selected. It should now appear in the sidebar of Finder.
macOS Method #2: Mount the SD Card
Before your Mac can perform read and write operations on your SD card, it first needs to be mounted. Mounting typically happens automatically, similarly to Windows, which allows you to access it once it’s connected. If it hasn’t happened automatically, let’s do it manually.
These steps will demonstrate how to mount an SD card in macOS:
- Click the Spotlight Search icon, and search Disk Utility. Open the first result.
- Select your SD card from the left navigation pane, then select Mount.
macOS Method #3: Update the SD Card Drivers
Of course, you want to ensure the SD card and SD card reader drivers are up-to-date. If they’re not, your Mac is unlikely to pick it up. This is easily done through the System Preferences section.
Follow these steps to update drivers on Mac:
- Click the Apple icon in the top left corner of your screen, then select System Preferences.
- Click Software Update. If any updates are available, click Update Now to install them.
macOS Method #4: Format the SD Card
If your SD card is at least recognized by your Mac, but not accessible, you can try formatting it to repair any damage that is preventing you from accessing it.
- Click the Spotlight Search icon, and search Disk Utility. Open the first result.
- Select your SD card, then click Erase.
- Enter the label and format for the SD card, then click Erase.
- Click Done.
Methods for Android Phones
While the microSD card slot found in smartphones is gradually being phased out by manufacturers, many phones still continue to rely on them for expanded storage space. Therefore, Android smartphones from tech giants like Samsung, LG, Xiaomi, and OPPO, often include built-in methods for fixing a microSD card that may be acting up.
Android Method #1: Remount the SD Card
Before your device can use an SD card, it first needs to be mounted. More modern smartphones do this automatically, but older ones may need to be done manually. If your SD card is already mounted, you can try unmounting it (ejecting it) then mounting it again.
Here are some general steps for mounting an SD card, but they will differ slightly based on the device:
- Access your Settings.
- Go to Storage.
- Tap SD card, then select Mount. If your SD card is already mounted, try tapping the Eject icon next to it, removing it, then connecting it again before remounting.
Android Method #2: Format the SD Card
There are benefits to formatting your SD card directly from your Android device, such as knowing that the correct file system will be installed. It also allows users to format their SD card if a computer isn’t available.
