If that’s what you’re experiencing, then you’ve come to the right place and we will try to help you get that fixed. Whether it is an SDcard, USB stick or flash drive, here is how you can resolve this issue in no time.

Remove from Read-only or Lock Mode

One of the solutions to your Windows being unable to format that removable drive might be to remove the active read-only mode on the drive. In the case of an SD card, it might be as simple as sliding back a lock switch somewhere at the side which makes it only readable. However, in other cases, you would have to remove the read-only or write protection using command prompt. To do this, follow the steps highlighted below:

  • Next thing to do is type ‘attribute disk‘ to see the properties and if you see ‘Current Read-only State: Yes‘, then that means your computer is not allowed ‘write‘ access which is why you’re unable to format the drive.
  • To change that, type ‘attributes disk clear readonly‘ and hit enter. Close the window and try to format the drive again.

  • After doing that, you will need to create a ‘simple volume‘ by selecting the drive and clicking on ‘New Simple Volume‘, then following the prompts.

Error Check and Repair Drive

Another reason you might encounter formatting errors is because of the bad configuration of the flash drive and you can check if that is the case in order to perform a repair.

To check, all you have to do is right-click on the removable drive and click on ‘Properties‘. In the resulting tab, navigate to ‘Tools‘ and click on ‘Check‘ under ‘Error checking’. If there is an issue with your removable drive, a small window will come up with the option to ‘Repair drive”. Go ahead and do that, then try formatting it again.

Summary

If after doing all this, you are still unable to format the drive, you should consider formatting it with another OS like Linux or macOS. Ultimately, the next obvious thing to consider is that the removable drive might actually be bad and you should get another one.
