7 Ways to Format Corrupted SD Card in Windows 10/8/7

SD card is a popular storage device which is widely used in Mobile phones, digital cameras, and other devices to extend internal memory. But sometimes, it might become unreadable, corrupted, damaged, or has some kind of error. When this happens, you are not allowed to access the card and the files on it. To format a corrupted SD card without losing data, before starting out with the below solutions, try to use memory card data recovery software to recover data from the inaccessible SD card in the first place.

A corrupted SD card is usually upon failing, so you need to apply fixes as soon as possible. From our point of view, most SD card corruption issues are developed from virus damage, file system corruption, outdated driver or bad sectors. Accordingly, we'll present you seven universally applied solutions to fix a corrupted, damaged or unreadable SD card. 

7solutions to format corrupted sd card

Solution 1. Try to Use SD Card on Another PC

When your SD card starts malfunctioning, it's not 100% likely that it's corrupted. Maybe the issue is specifically on your PC. Try connecting your SD card or other generic removable drives to another computer. As long as the SD card can be normally read and accessed on the other computer, you should turn back to your own PC and check what happened.

Solution 2. Change the Drive Letter

Though sounds unfamiliar for you, it's quite often to see driver letter confliction between a local drive and a removable hard drive (e.g. SD card, USB flash drive, pen drive and external HDD). When there is a confliction, your computer will find it difficult to assign an appropriate drive letter to your storage media, without which your SD card will be totally invisible. To resolve this issue, you can manually assign a drive letter to your device.

You can either change a current drive letter or assign a new one in Windows Disk Management as well as a third-party partition manager, which you'll find in the fourth solution.

However, it's comparatively the most essential and basic Windows formatting tool that can only handle minor corruption issues. For example, if you want to format a 64GB SD card to FAT32, Windows Explorer is in no vail. While third-party SD card formatter software will be more powerful than formatting a corrupted, damaged or unreadable removable disk, HDD or SSD, it always provides customers with many more auxiliary disk and partition management features.
