SD Card Repair on Windows 10

You may have a problem with a functioning SD card malfunctioning without warning. But most SD cards show some symptoms of damage before they stop working. So let's find out together.

Sign 1. SD Card Not Showing Up

If your SD card isn't being detected, it could be due to a dirty SD card interface, a rusted or twisted card slot, a virus on the SD card, or a broken SD card. To resolve this, try wiping the metal part of the SD card with an eraser, ensure the device is turned off when inserting or removing the card, and regularly run a comprehensive scan and antivirus on the SD card.

If you've completed the initial troubleshooting steps but the SD card still isn't being detected, there are additional advanced solutions you can try.

Sign 2. SD Card Showing Wrong Size

To resolve the issue of your SD card not showing its full capacity, you can try formatting it. This process will erase all data on the card, so make sure to back up any important files first. To format your SD card, insert it into your computer or a card reader connected to your computer. Open the file explorer, right-click on the SD card, and select 'Format'.

SD cards may show the wrong size due to unsupported large-capacity SDHC or SDXC cards in readers or devices, causing partitioning to the supported capacity, such as 32GB, instead of the actual capacity, like 64GB.

If you suspect your SD card is damaged, look out for signs like read/write issues, connection problems, or formatting troubles. If you catch the issue early, you can back up your data and try repairing the SD card using methods available on Windows 10.

Fix 1. Fix Corrupted SD Card Without Formatting 

If your SD card isn't being read or recognized on your Windows computer, you can fix the issue without formatting and losing your data. First, try connecting the SD card to another computer to see if it can be read. If not, try using a different SD card reader or a USB adapter, which may resolve the problem.

If the method fails, you can try repairing the corrupt SD card using the CHKDSK command or the disk error checking tool embedded in Windows 10, or use the Windows Troubleshooter, reinstall the SD card driver, update the outdated SD card driver, change the drive letter, or contact the manufacturer for SD card repair.

Fix 2. Format SD Card Without Data Loss

If the basic solutions don't work, you can try using data recovery software to retrieve files from the SD card and then format the SD card using your computer's built-in utility or a third-party software program.

Deep Data Recovery is a tool that enables quick restoration of files from corrupted, damaged, inaccessible, or RAW SD cards, as well as other devices such as USB flash drives, external hard drives, and laptops.

Step 1. Press Windows + E to open File Explorer.

Step 2. Right-click on the corrupted SD card and choose "Format".

Step 3. Select a file system as you need and click "Start" to begin the process.

Fix 3. Repair RAW SD Card

A removable storage device such as a USB drive or SD card suddenly cannot be detected or accessed. When trying to access it in File Explorer, it prompts to format it, and in Disk Management, the file system type is shown as RAW instead of NTFS or FAT32.

An SD card can become RAW due to various reasons, such as removing it without clicking "Safely Remove Hardware and Eject Media", pulling the disk out, shutting down or restarting the system while it's still reading and writing data, or experiencing unstable power supply from the computer's USB port, leading to disk I/O errors.

If your SD card is stuck in RAW format, you can fix it by recovering any important data first using data recovery software, then formatting the device. Alternatively, if there's no critical data on the card or it's been backed up, you can skip the data recovery step and perform the SD card RAW format fix directly.

SD Card Repair on Android

If your Android phone's SD card is formatted or corrupted, you may be wondering how to recover photos and repair it. Unfortunately, it's not uncommon for SD cards to become damaged, displaying issues such as being unreadable or displaying an error message. However, there are steps you can take to potentially recover your photos and repair the SD card.

Case 1. SD Card Photos Not Showing Up in file///SDcard/gallery

The Android operating system uses the file path "/SDcard/gallery" to store images taken with the camera and downloaded from the internet on an SD card, typically used in devices without internal storage like tablets and smartphones. This path is case-sensitive.

Many users have reported that their photos and videos on the SD card are not showing up in the file:///SDcard/gallery. The possible reasons for this issue include incompatible file formats, file corruption, or damage to the SD card.

Case 2. SD Card Not Detected Android

If an SD card is damaged, it may not be recognized by a PC or Android device, or even worse, it may be accidentally formatted. SD cards can become corrupt on Android due to various reasons, with logical errors being a common cause. This can happen when the card's file system becomes corrupted or there are bad blocks on the card, often as a result of not properly ejecting the card from the device before powering off.

Malicious attacks can also cause Android SD card corruption and data loss, so it's essential to be vigilant about keeping your device clean.

How to Fix Corrupted SD Card on Android 

It can be frustrating when trying to view specific photos or groups in the gallery, only to find them missing or the SD card undetectable on Android.

If you suspect your SD card has become corrupt, ensure it's properly inserted into your device, and try restarting it to refresh the file system and allow it to see the new content on the card.

If restarting your device doesn't work, you may need to format the SD card, which will erase all data on the card, so back up any important files before proceeding. To format an SD card, you can follow the device's instructions or use a computer to initialize the card, which will erase all data and restore it to its factory settings.

Step 1. Open the "Settings" app and go to the "Storage" section. 

Step 2. Tap on the SD card, then tap the "Format" button. 

Step 3. Confirm that you want to format the card and wait for the process to complete.

If you're experiencing issues with your gallery app, try fixing the problem first. Once that's done, add some new photos to the app and check if they appear in the file:///SDcard/gallery. If the SD card is still not detected, you may need to perform a factory reset, but make sure to back up your data before doing so.
