Error: Windows 11 Won't Let Me Format Hard Drive

If you've formatted a USB flash drive or hard disk on a Windows computer but were unable to complete the formatting process for some reason, and Windows prompts you to fix the drive partition or that it can't remove the software protection (DRM), I recommend some straightforward steps that are more likely to resolve such issues and fix problems caused by an incomplete format.

Before attempting any of the following Windows fixes, make sure to back up important files from the drive you can't format. You can use Windows' built-in backup tools or Todo Backup disk imaging software.

Case 1 - Windows Unable to Format USB Drive

My computer's hard drive is running out of storage, so I decided to use a blank USB flash drive to create more available space. When I inserted the flash drive into my laptop and tried to format it as FAT32, I encountered a partition error, which now prevents Windows from formatting the USB again.

Scenario 2 - Windows Failed to Format Hard Disk Partition or Drive

You've created a partition on your hard drive to install a second operating system (OS). Now, when you try to format the recently created partition, you receive a message stating “Windows 11 can't format the drive.” What does this error mean, and how can you fix the “Windows can't format the hard drive” issue in Windows 11?

I am stumped when I get an error message telling me that Windows was unable to complete the formatting of my hard disk. Of course, Microsoft knows something that I don't. But let's get to the heart of the matter.

Why can't I format a hard drive in Windows 11?

Many factors can eventually lead to this error. It is recommended to check all these factors before you perform any formatting operation. This ensures that your formatting process is safe and carries no risks.

There can be numerous reasons why you can't format a hard drive in Windows 11. If you're having issues with formatting, you might want to check if any of the following scenarios apply to your situation:

1. The hard drive is write-protected.

Before you begin formatting the drive, make sure it's not write-protected. Write protection prevents the disk from being overwritten or altered in any way. You can easily remove the write protection from your drive using the diskpart method mentioned below.

2. File System Error – The current file system is not supported by Windows.

When Windows 11 encounters an unsupported file system, it may display the hard drive as RAW and render it inaccessible. For instance, if the drive is formatted in Linux's Ext2/3/4 instead of FAT, NTFS, or exFAT, Windows will refuse to format it.

To resolve this issue, you can use a third-party formatting tool to help format the device in Windows 11.

3. Viral infections

When your USB or hard drive is having connectivity issues, it could be a sign of a virus attack. This is because the data on the drive becomes inaccessible and eventually leads to the corruption of the entire drive. Upon encountering this problem, you should take immediate action to rid the drive of the virus.

4. Hard drive is offline, unallocated, or unknown

Windows 11 cannot format a hard drive without partitions because formatting is a partition-based process that requires a partitioned volume to create a file system.

The easiest solution is to convert the unallocated space on the removable disk back into a partition.

5. Windows is unable to format the system partition on the target disk

The most severe reason behind this error is corrupted system files. Usually, this becomes an issue when you run out of disk space or attempt to format an incorrectly identified encrypted drive. In such cases, you must check and repair the damaged system files.

6. Hard drive has bad sectors

Windows is unable to format a hard drive with bad sectors. Bad sectors on a hard drive can be caused by various factors, such as power fluctuations during operation, excessive defragmentation, and more.

You can perform simple repairs on a disk drive by using standard Windows utilities, such as Disk Error Checking and Bad Sector Repair.

7. Drive Physical Damage

Most of the times, hard drive unaccessibility issues are due to hardware failures like disconnected/broken IDE/SATA cable or physical damage to the disk. There's nothing you can do about it and you will have to purchase a new one.

How to Fix the "Unable to Format Hard Drive" Error in Windows 11

Backup all crucial files from the target hard drive beforehand, and then follow the instructions and tutorials below to resolve the "Can't Format Hard Drive" error in Windows 11.

Method 1: Use a Third-Party Formatting Software - Partition Master

The partition manager tool is a program that allows you to format hard disk partitions to FAT32 or NTFS.
