“The SD card won’t format even though I bought it a couple of weeks ago. I use this SD card mainly to store my photos taken with the Samsung phone I use. I am not sure what has happened with the SD card.

And I cannot figure out if it is infected with a virus or corrupted in another way. When I connect the SD card to the computer, it says the card should be formatted. Even if I lost data, I tried to format the card through the PC.

But I continuously get the message saying 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 occurs 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 huge.

Here, we intend to explain how to resolve this matter.

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

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

When an SD card has 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 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 could 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 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.

PS: let’s figure out how to format the SD cards on Android.

What Should You Do if Your Sd Card Won’t Format?

05. Remove the Write Protection If the SD Card is Write-protected

As we have mentioned, your SD card won’t format if it is write-protected. This is true for hard drives and even for USB flash drives.

This could be the reason for a large number of users experiencing an “SD card won’t format” issue. It can be seen on mobile devices as well as on PCs.

So, if this is the case, you should try to remove the write protection from the faulty SD card. You can either use the CMD interface or EaseUS. Those who aren’t familiar with the command lines can rely on EaseUS.

06. Check for Bad Sectors and Repair Them.

There can be bad sectors on your storage media, but there are invisible ones. However, they will prevent you from accessing the data on the device and using the existing files.

To get rid of the bad sectors, you can simply format the respective disk. Well, what if you cannot directly format the faulty SD card that has bad sectors in your Windows PC?

In that case, you should run the command lines to check the number of bad sectors. After that, you can repair them all. Once you have removed the bad sectors from the SD card, it’s time to format it.

  • Invoke the Run utility by pressing the Windows key + R keys at the same time.
  • Then, enter the text cmd in the Run box. After hitting Enter, you will see the command prompt.
  • Once in the command prompt, just enter chkdsk E: /f /r /x. Replace the letter E with your SD card’s actual drive letter.

Other Instances in Which You Cannot Format an SD Card

01. Fixing a RAW SD Card that Cannot Be Formatted

Do you see the SD card in RAW when you have checked it in Disk Management? If so, you should first convert the RAW file system to NTFS or FAT32. Otherwise, you cannot use it normally.

So, to convert a RAW SD card to NTFS or FAT32, you should go for a disk format. You can easily fix this issue with the assistance of Disk Management by using the methods we have mentioned earlier. For instance, you can either use Command Prompt or EaseUS Partition Master.
