We introduce the possible means of solving the ‘Windows was unable to complete the format’ error, as well as some useful information about the reasons why such an issue might occur. We hope that the steps below will be exactly what you need to get this problem fixed and avoid throwing your USB Drive away.

Symptoms and possible origins of the ‘Windows was unable to complete the format’ issue

The ‘Windows was unable to complete the format’ warning might appear when your USB Drive turns out to be inaccessible for a certain period of time. As a result, it cannot be properly and fully formatted. In fact, such problems are becoming more and more common as USB drives and memory cards have become very popular means of storing data. However, sometimes they need to be completely formatted and at that point you may have become a victim of such an issue. The potential reasons for that are listed below.

  • Malware contamination. You can easily move data from a device to another one both via a USB drive or a memory card. That’s why it is very likely that they could get infected with an unpleasant malware type. Consequently, the virus makes them stop working and you cannot format them.
  • The affected storage device might be physically damaged. Some of the storage device’s components that you are using might have faced some kind of physical damage. As a result, your computer might refuse to format the damaged device. In such a case it is always cheaper and better to buy a new device.
  • The affected device is write-protected. Never will you be able to format any drive or disk that has been write-protected. Formatting is a version of a writing activity, so performing it will be impossible. Remove the protection if possible and then try again. Maybe this will be the solution to your problem.
