USB flash drive or SD card can store a large amount of data into it, but there are times when you need to format these devices, but an error pops up that reads like "Windows was unable to complete the format." If you are facing a similar issue, we are here with effective quick fixes that will help you solve this issue in minutes. But one critical thing to note here is that, before opting for any of the methods, make sure to recover the data from the inaccessible disks.
So, let's start then!
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.
As you have got to know the reasons behind the "Windows Was Unable to Complete the Format" error in Windows 11 PC, so it's time to learn the effective ways to solve this issue!
Besides Windows 11 explorer, there are other workable methods that you can use to perform a quick format, including Windows disk management and Windows command prompt. In addition to these Windows native programs, a third-party partition manager tool can help format a drive in just a few minutes.
