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

If you formatted your USB flash drive or hard drive on a Windows computer but failed to complete the format in certain situations. And, you are being asked by Windows to repair the drive partitions or are unable to remove software protection (DRM). Then, I will recommend some easy steps that are more likely to work for this purpose and can fix problems caused by incomplete format. 

Before trying any of the Windows fixes below, make sure to back up important files from the drive you are having trouble formatting. You can use the Windows built-in backup tool or EaseUS Todo Backup disk imaging software.

Case 1 - Windows cannot format the USB Drive

My computer's hard drive ran out of storage, so I decided to use a blank USB flash drive to create more available space. Now, when I inserted the flash drive into my laptop and tried to format it with FAT32, a partitioning error got stuck and Windows started to fail to format the USB again.

Case 2 - Windows cannot complete format hard disk partition or partitions

So, you have created a partitioned hard drive in an attempt to install a second operating system (OS). And now, when you attempt to format the most recently partitioned drive, you receive the message that "Windows 11 Can not format the drive." What exactly does this error mean? How to fix this "Windows Can't Format Hard Drive" error in Windows 11?

When I receive an error message that tells me Windows cannot complete the format of my hard drive, then I'm in a quandary of epic proportions. Certainly, Microsoft knows something that I do not. But let's get to the meat of this problem and resolve it once and for all. 

Why Can't I Format Hard Drive in Windows 11 

Numerous factors would ultimately result in this error. We advise you to explore all of them before carrying out any format procedure. This way you can confirm your format undertaking is safe and free from risk factors. 

There is an array of reasons why Windows 11 cannot format the hard drive. If you're having trouble formatting your hard drive, you might want to check whether the reasons below fit your issue:

1. Hard drive is write protected

Before you start a hard drive format, make sure it is not write-protected. Write protection prevents the drive from being written over or changed in any way. You can easily remove the write protection from the drive using the below-mentioned diskpart method.

2. File system error - the current file system is not supported by Windows

When Windows 11 encounters an unsupported file system, it can display the hard drive as RAW and inaccessible. For example: if the drive format is Linux Ext2/3/4 instead of FAT, NTFS or exFAT, Windows will refuse the formatting operation.

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

3. Virus infection

Whenever your USB or Hard drive is making issues while being connected, it is a sign of virus infection. It happens because data on the hard drive cannot be accessed and ultimately blocks the whole hard drive. When this problem occurs, you should take immediate action to make the drive virus-free.

4. Hard drive is offline, unallocated, or unknown

Windows 11 cannot format a hard drive if it does not contain any partition. This is so because the formatting is a method based on partitioning that requires a partitioned volume to create a filesystem. 

The easiest way to correct this problem is to convert the unallocated space on your removable disk back into a partition. 

5. Windows cannot format the system partition on the target disk

The most serious reason behind this error is system file corruption. Usually, it becomes a reason when disk space is less or when you are trying to format an encrypted drive that is not in the correct position. If this problem arises, you must check and repair the damaged system files.

6. Drive Has Bad Sectors

Windows can not format hard drives that have bad sectors. Bad sectors on hard drives can be caused by several factors such as power fluctuations during the program run, excessive defragmentation, and so forth. 

You can perform a simple repair using the standard Windows utilities like Disk error checking and a bad sector repair tool to fix the errors on your disk drive.

7. Drive Is Physically Damaged

In most cases, hard drive inaccessible issues can occur due to hardware failures like an IDE/SATA IDE cable is disconnected/damaged or the disk is physically damaged. There’s nothing you can do about this. You must buy a new hard drive. 

How to Fix "Can't format Hard Drive" Error on Windows 11

Method 1. Clean Virus or Malware and Format Hard Drive
