Causes of Memory Card Corruption

Memory cards can become corrupted for a variety of reasons, including:

• 🧑 Human factor: Here’s an interesting fact: humans are responsible for most cases of SD card corruption. Even though we don’t like to admit it, we’re often lazy to properly eject our SD cards before removing them, and we also have the tendency to use the same SD card in multiple devices even though we know that we shouldn’t.
• 🐛 Malware and viruses: Many viruses and malware are designed with the intention of destroying files or corrupting the storage media with which they come in contact. Especially exposed to malware and viruses are memory cards in smartphones and other mobile devices because their users often download apps and files from the internet.
• 🌎 Environmental factors: Excessive heat and moisture can cause any SD card to become corrupted. These small storage devices are not meant to be durable, and they can easily be damaged if not properly protected and stored.
• 🏭 Manufacturing defects: Except for their storage capacity and data transfer speed, all SD cards seem more or less identical. However, there’s a huge difference in how reliable bargain bin versus brand-name SD cards are. To avoid corruption caused by manufacturing defects, you should always pay extra for SD cards from reputable manufacturers, such as SanDisk or Lexar.
• 👩‍💻 Software errors: Memory card corruption can also be caused by buggy software, which is why it’s a good idea to first copy files from your SD card to your computer before you start editing them.

Methods to Fix SD Card Corruption Without Software

Here are some tried and tested methods that you can use to fix a corrupt or unresponsive SD card. To save time, we recommend you try the methods in the order they’re listed.

– Fix 1: Try to connect the SD card to another device

Solution:
There may be nothing wrong with the SD card itself. The issue may be in the device containing the card. To see if this is the case, take the card out of the device and try it in a different device or your computer’s card reader to see if you can access its data.

– Fix 2: Use the chkdsk command to attempt a memory card recovery

– Fix 3: Fix any drive letter compatibility issues

Solution:
You may need to assign a new drive letter to your card. The letter it currently has may be in use or is not recognized by your operating system. Follow this procedure:

1. Open Disk Management.
2. Right-click the card whose letter will be changed.
3. Click Change Drive Letter and Paths.
4. Select the Change button and choose from the list of available drive letters.
5. Click OK.

– Fix 4: Format the SD card

Solution:
Use this procedure to format an SD card:

1. Open Windows Explorer.
2. Find the drive letter for your SD card.
3. Right-click the card and select Format.
4. Select FAT32 or exFAT for larger drives.
5. Click Start.
6. Click OK when notified the data on the card will be deleted.

– Fix 5: Reinstall the device driver software

Solution:
You can try to uninstall and reinstall the device driver software for the device which contains the card that cannot be read. This may resolve the problem and indicates that the card itself has not been damaged.

Recommendations to Protect your SD Card

Protecting your SD card is really a matter of exercising caution and common sense. Some suggestions that can minimize the chances of losing data from your SD card include:

• Keep your SD card in a storage case when not in use: SD cards are fragile—perhaps too fragile considering the massive amounts of data they can store these days. To prevent your SD card from becoming physically damaged, we highly recommend you keep it in a storage case when not in use.
• Make sure your SD cards are properly organized: Many people simply throw their SD cards inside a camera bag or drawer without organizing them in any way. That’s a bad habit because it makes it really easy to pick the wrong card and accidentally format it. Even if you’re in a hurry, you should always take the time to organize your SD cards.
• Use one SD card for just one device: Some devices, such as certain cameras and smartphones, are greedy and don’t like when they don’t have the entire SD card for themselves. To avoid issues with data corruption, you should always use one SD card for just one device.
• Lock your SD card when you’re done using it: The mechanical lock located on the left side of most SD cards makes it impossible to delete or modify any data. As such, you should take advantage of it whenever you’re done using your SD card to avoid accidental formatting.
• Safely eject your SD card: Removing an SD card from your computer or camera before all data has been written can cause the same data to become unreadable, so always take the time to safely eject your SD card before you physically disconnect it.

If you remember and practice these five simple suggestions, your chance of losing important files will be far lower than it would be otherwise.

Why You Should Use SD Card Repair Software

The main reason why you should use SD card repair software is that it provides you the most reliable method for recovering data from a corrupted SD card.

Software recovery tools allow you to get back important photos and files that cannot be restored through native Windows features or other means. An application like Disk Drill can get back photos that you thought were gone forever with a few simple steps—no special knowledge or skills required.

What’s more, the best SD card repair software lets you preview recoverable files (and sometimes even recover at least some of them) free of charge, so there’s no reason not to give SD card repair tools a try.
