Why I am unable to format a usb stick after using rufus

Question

I used Rufus to create a bootable USB, but now I cannot format the drive back to normal. Windows Disk Management and the regular format tool both fail. They either give an access denied error, show the drive as write-protected, or only offer RAW format. The drive does not appear with its full capacity. I've tried the quick format option and full format in Explorer without success.

I am now completely unable to formate a usb stick after using rufus. What steps can I take to completely wipe this USB and restore it to a single, usable FAT32 or NTFS partition? I am on Windows 10.

If you are unable to format USB after using Rufus, using Windows Disk Management might seem like a straightforward solution. However, in many cases, Disk Management alone cannot resolve the issue, especially if the drive is write-protected, corrupted, or has a damaged partition table caused by Rufus.

Why Disk Management Might Fail

Disk Management may not display the full capacity of the USB or show it as "RAW."
It may refuse to format the drive, giving errors like "Access Denied" or "The disk is write-protected."
Any residual bootable or partition data created by Rufus can prevent standard formatting.

Using Disk Management if unable to format USB after using Rufus:

1. Open Disk Management:

Right-click the Start button and select Disk Management.

Or press Win + X and choose Disk Management.

2. Locate your USB drive:

It may appear as Removable or with a specific drive letter.

The drive might show as Unallocated, RAW, or with a partition that cannot be deleted.

3. Attempt to delete the partition:

Right-click the partition on the USB and select Delete Volume.

If this option is greyed out or fails, it indicates a deeper issue such as write protection.

4. Create a new volume:

If the partition is successfully deleted and the space shows as unallocated, right-click it and select New Simple Volume.
