“You need to format your drive before you can use it.” The dreaded error message will come up sooner or later, so you should know how to fix it – especially since going ahead with the format means that you’ll lose your data. On the other hand, ignoring it may also lead to eventual data loss.

Fortunately, this is a common error and there are proven methods to fix an SD card without formatting. This article will teach you how.


Pro tip: Formatting your SD card in the first instance is a drastic measure. Don’t do it until you have read this article. Click here to jump straight to the recovery section.

Why Your SD Card Asks to Be Formatted

In reality, many factors can lead to this error. But figuring out what caused it in your case may help you find the solution faster. Here are some of the usual culprits:

  • 🦠 Corruption. Corruption can prevent your SD card from properly functioning or your computer from recognizing it. Corruption happens due to virus attacks, interruptions to the read/write process, improper ejection, and other logical damage. Fortunately, there are ways to “uncorrupt” an SD card, and even recover files from a corrupted SD card using the methods in this article.
  • 🔥 Physical damage. When not handled with care, you can easily bend, twist, and crack your SD card. When you disalign the metal pins of an SD card, you create connection issues between the devices. Dust and debris can also get in the way of connectors.
  • Fake Product. Fake SD cards are lower in quality and often misrepresent either their storage capacity or read/write speeds (or both). When you buy a fake product, you can’t really predict how it will perform.
  • ⚙️ Outdated drivers. Drivers help your operating system read the external drives. Hence, an outdated one can make your SD card unrecognizable.
  • 🔄 File transfer interruption. If a file transfer is interrupted (for instance, by a power outage or removing the card in the middle of a transfer), the card’s file system may become corrupt, requiring the card to be formatted.
  • ⚠️ Conflicting Operating System and Card Format: You could be prompted to format the memory card if it was previously used on a device with a different operating system than the one you are currently using. This happens because different operating systems use/can read different file systems.

How to Retrieve Data From SD Card Without Formatting

Before attempting to fix your SD card, we highly suggest that you retrieve your data first. Handling a problematic storage device can often make things worse. And if you do end up having to resort to formatting (such as in the case of severe virus infections), this will wipe all the data on your drive.


While there are cases where you can still recover some or even all of your data after formatting your SD card, this article is about avoiding a format – so read on.

How to Fix Corrupted SD Card Without Formatting

Formatting an SD card completely wipes your data… You probably don’t want that. Fortunately, there are ways to repair a corrupted storage device without having to format it.

The first step in fixing a corrupted SD card without formatting is to make sure it is readable. Your operating system should be able to recognize it in Device Manager, even if it doesn’t appear in File Explorer. As long as it shows up in Device Manager, you can try one of these 6 methods.

Method 1: Try using another device (e.g. USB Port, Card Reader, or PC)

This method is a collection of quick fixes just in case the problem is mechanical:

  1. Check the sides of your SD card for a small, physical switch. This locks and unlocks your SD card – this is what it looks like. Try unlocking it and reconnecting it to your computer.
  2. Use a dry, microfiber cloth to clear your SD card and/or ports of any dust and debris.
  3. Use another port, SD card adapter (if you are using a micro SD card), or an entirely different computer and see if the error appears.

Method 2: Assign a New Drive Letter

A faulty OS update or even a laggy computer can mess up drive letter assignment. If your SD card isn’t showing up in File Explorer, it may have a conflicting letter with a local drive or it might not even have one.

To assign/change the drive letter, follow the steps below:

  1. Hit (Windows key + X) and select Disk Management. Quick access menu
  2. Right-click on the corrupted SD card. And select Change Drive Letter and Paths from the drop-down list.Change drive letter and paths button
  3. Click the Change button.Change button in the Change drive letter and paths dialogue box
  4. Assign a letter and click Okay to apply changes.Drive letter dropdown menu

Method 3: Reinstall SD Card drivers

Windows automatically installs drivers. But things can still go sideways and we can end up with a faulty driver update during the process. The fix here is to uninstall the current driver first. Then, you can reinstall the latest driver from the web – automatically or manually.

Here’s how you do it:

  1. Hit (Windows key + X) to open the Quick Access Menu.
  2. Select Device Manager.Device Manager in the Quick access menu

  4. Right-click on your SD card and select Update Driver.Update driver button
  5. Select Search automatically for updated driver software to begin the scanning process.Search automatically for drivers button in the dialogue box
  6. Click Update Driver.

To manually update the driver, go to the manufacturer’s website. From there, you can look for and download the latest driver.

Method 4: Use CHKDSK Command

If none of the previous methods work, you can try using the command line to check for any memory card error. We can’t guarantee that your data will be 100% intact after the process. It is best to recover your files and backup your data first before trying this method.

If you want to use CHKDSK to fix your SD card, follow the steps below:

  1. Hit (Windows key + X).
  2. Select Command Prompt (Admin) [or PowerShell (Admin)] to run as administrator. Alternatively, you can type cmd in the search bar at the lower-right corner of your screen. Windows Powershell (Admin) button in the Quick Access Menu
  3. Type this command: chkdsk drive letter: /f (Don’t forget to replace “drive letter’ with the actual one, like so: “chkdsk E: /f”). Then, press the Enter button. Wait for it to finish.chkdsk command in Powershell
  4. If the system detects bad sectors, you will receive a notification. When this happens, type Y and hit Enter again to begin restoring the file structure of your SD.
  5. Wait for the process to finish, which may take a few minutes to hours, depending on the size of your SD card.

Method 5: Use Windows Repair Tool

The Windows Repair Tool is a built-in utility that can check for any errors in the file system. If this doesn’t pop up automatically, you can manually launch it by following the steps below:

  1. Open File Explorer.
  2. Select This PC on the left sidebar. This PC button in File Explorer
