FIX: Steps to Fix “Windows Could Not Format” SD Card

Memory card is a very convenient and reliable device to store and move files, photos, and videos. Nowadays, most mobiles and cameras have the option to extend device memory with a memory card. However, your memory card is not as reliable as your device’s internal storage or a computer hard drive. I recommend to backup your memory card periodically if it has important files.

Sometimes, when you attach your memory card to your computer, you receive a message that your memory card needs to be formatted. Before you proceed with the format, make sure that it does not contain important files. If you choose to format, Windows will try to format the card. However, in some instances, Windows will show you a message that Windows could not format memory card/sd card.

In this guide, we will list a couple of methods to resolve the issue.

Check If the SD Card and the Card Reader are Working

Remove your memory card from the computer and insert another memory card in the same external or internal memory card reader device. If other cards are working properly, you can be sure that the card reader is working properly. Attach your memory card to another computer or device to check if it is working. If your card is good, you can move to the next step to format it.
