But I am continuously getting the message saying that it cannot format the SD card. Can any expert help me out? Please!”

The above paragraph is just a single example that shows an issue associated with SD cards. This issue takes place when you try to read the SD card with the assistance of a computer. When you insert the SD card, the PC says that the SD card won’t format. As of today, SD cards are becoming incredibly popular because of their miniature size. So, if you’re using an SD card to store valuable data, the above issue can be a huge issue. Here, we intend to explain how to resolve this matter.


What can cause the issue “SD card won’t format.”

Before we go to the solutions, it is better to take a look at the reasons behind this issue. There are a couple of general reasons behind this issue, and let’s take a look at them.

When an SD card runs into problems and wants to be formatted, there’s something wrong with its file system. In other words, the requirement to be formatted can appear due to a file system incompatibility.

  • For instance, some devices use only the FAT32 SD card.
  • Also, the SD card file format can suddenly turn raw.
  • Windows simply cannot recognize the SD card you have inserted.
  • The SD card doesn’t show up as a mass storage device. Instead, it may appear as an unallocated space.

And so on.

Nevertheless, the error message you see would say that the respective SD card should be formatted. Even though the system says so, the same system doesn’t allow you to format the SD card. According to the research, however, we were able to end up finding several causes behind this issue.

  • The SD card you are trying to format is write-protected. As a result, Windows cannot make any changes to it. So, you cannot format your SD card at all until you remove the write-protection.
  • SD card is with bad sectors, or it has corrupted due to some reason. As a result, Windows cannot necessarily format a corrupted SD card.
  • You are using the SD card on various devices and computers. As a result, malware such as viruses can enter your card and make it inaccessible. When the card is infected with a virus, you cannot format the SD card.
