An SD card can become corrupted due to different causes. Most common include physical damage, logical corruption, or a file system error. Physical damage can occur if the card is dropped or otherwise physically damaged. And the logical error appears when the SD card is improperly removed from a device or becomes infected with a virus. The file system issue will arise when the SD card is formatted incorrectly or becomes RAW.

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
You insert the SD card into a digital camera or computer, but why can't it be detected? The SD card not showing up may be because the SD card interface is dirty, the card slot is rusted or twisted, the SD card is infected with a virus, or the SD card is broken. In these cases, you can use an eraser to wipe the metal part of the SD card, or be sure to insert and remove the SD card when the device is turned off and perform a comprehensive scan and antivirus on the SD card regularly.
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
"My SD card not showing full capacity. How can I format the memory card back to the correct capacity?"
The main reason SD cards show the wrong size is that some card readers or host devices do not support large-capacity SDHC or SDXC memory cards. If the card reader or device does not support large capacities, the memory card will be partitioned to the capacity supported by the card reader or host device. For example, suppose the card reader supports SDHC memory cards with a maximum capacity of 32GB. In that case, formatting a 64GB SDXC memory card with this card reader will cause the card to be repartitioned to 32GB, which is far less than the actual capacity of the SD card.
Other possible indications of SD card damage include read/write problems, connection matters, formatting troubles, etc. If you find the issue beforehand, you can back up your data in time and use the following methods to repair the SD card on Windows 10.
Fix 1. Fix Corrupted SD Card Without Formatting

Fix 3. Repair RAW SD Card
Sometimes, removable storage devices such as USB drives or SD cards cannot be detected or accessed suddenly. When we double-click the disk in File Explorer, it will prompt that it is not formatted, and the system will ask whether to format it. If you open Disk Management, you will see that the file system type of this disk is no longer the usual NTFS or FAT32 but RAW format instead.
There are many reasons why an SD card becomes RAW, including when we removed the SD card. Instead of clicking "Safely Remove Hardware and Eject Media", we pulled the disk out. Or directly shut down or restart the system when the SD card reads and writes data usually. Or the power supply of the computer's USB port is unstable, resulting in disk I/O errors.
The correct process for fixing the RAW SD card is to recover the data first with EaseUS Data Recovery Wizard, then format the device. Of course, if there is no critical data on your SD card or the data has been backed up, you can perform the SD card RAW format fix directly.
