What Is "Windows Was Unable to Complete the Format" Error Message?

Before we get to the possible solutions to fix the "Windows Was Unable to Complete the Format" error, we would like to present the possible reasons that could cause this error. In this way, you'll be able to avoid the possibility of getting such an issue. In general, five reasons may lead to the "Windows Was Unable to Complete the Format" error in Windows 11 PC that involves:

The Drive is Write Protected

Formatting the drive is a writing operation; therefore, you need to remove the write protection first before formatting the drive. Try to copy something to the drive, and if you see the following message "The disk is write-protected," it means that the drive is write-protected, and hence Windows will not be able to complete the format.

The Drive is Empty

Another reason that can cause this issue is that there is no partition on the hard drive, and the drive is empty. However, you'll find there is a drive letter for it. As formatting is entirely based on partition instead of unallocated space, Windows is unable to complete the format.

The Drive is Physically Damaged

Physical damage is another reason that could lead to storage devices being inaccessible, and therefore Windows requires formatting it. Bad spots can easily be repaired by a professional repair center, but the cost is not low at all.

The Drive Has Bad Sectors

All the files stored on hard drives generally occupy multiple sectors. So, if the sector is damaged and cannot be written or read, it is called a bad sector. The bad sector can affect the format operation and the data recovery operation.

The Drive Suffers From Virus and Malware Infection

Last but not least, the final reason for "Windows was unable to format the drive" is that the drive is suffering from virus and malware infection. The virus and malware often fill the USB drives with dangerous files that in turn make the drive out of service.
