SD Card Repair on Windows 10
If you're experiencing issues with your SD card, you're not alone. While some SD cards can malfunction without warning, many others show signs of damage before they completely stop working. Let's explore these symptoms together to see if we can identify the problem.
Sign 1. SD Card Not Showing Up
If your SD card isn't being detected, it's likely due to a dirty SD card interface, a rusted or twisted card slot, a virus-infected SD card, or a broken SD card. To resolve the issue, 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 have done all these, but the SD card still has the problem of not being detected, you can continue to try our advanced solutions below.
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 ensure you back up any important files before proceeding. You can format the SD card using your device's built-in formatting options, or if you're using a computer, you can use the disk management tool to format it. After formatting, the SD card should display its correct capacity.
SD cards may show the wrong size due to card readers or host devices not supporting large-capacity SDHC or SDXC cards, causing them to be partitioned to a lower capacity. For example, a 64GB SDXC card may be formatted to 32GB if the card reader only supports up to 32GB SDHC cards. This results in the card being displayed as having a lower capacity than its actual size.
The SD card may be damaged if it shows read/write problems, connection issues, or formatting troubles. If you identify the issue early, you can back up your data and use methods to repair the SD card on Windows 10.
Fix 1. Fix Corrupted SD Card Without Formatting
If your SD card is not reading or recognized on your Windows computer, you can fix the issue without formatting and losing your data. Try connecting the SD card to another computer to see if it's readable, and if not, try using a different SD card reader or a USB adapter. This can help you determine if the problem lies with the SD card itself or with the reader on your original computer.
If the method fails, you can fix the corrupt SD card using the CHKDSK command or the built-in Windows 10 disk error checking tool. Alternatively, you can 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 3. Repair RAW SD Card
Removable storage devices like USB drives or SD cards may suddenly stop being detected or accessed. When trying to access them in File Explorer, a prompt may appear saying they're not formatted, and the system might ask to format them. In Disk Management, the file system type of these disks is shown as RAW instead of the usual NTFS or FAT32.
An SD card can become RAW (read-only access) due to various reasons, such as removing the card without safely ejecting it, pulling the disk out while it's still in use, shutting down or restarting the system while it's still writing or reading data, or experiencing unstable power supply in the USB port, leading to disk I/O errors.
To fix a RAW SD card, it's essential to first recover any important data using data recovery software, before formatting the device. If there's no critical data on the card or it's been backed up, you can proceed with the SD card RAW format fix directly.
