Beware if you are planning to completely format and dispose of your Windows 10 or Windows 11 computer at this time. The built-in disk wiping functions do not work properly.
Format error on Windows systems
The error shared by the developer named Rudy Ooms states that there is an error in the Windows 10 and 11 21H2 data wipe tool. This error affects formatting both local and remote drives.
Ooms tested the format tool both remotely and locally on many Windows versions and got the same error. Although the tool seems to delete all your data, unfortunately it leaves residues. The bug is only present in version 21H2. The 21H1 version removes all data from the drive as expected. Since there is no explanation from Microsoft yet, it is useful to pay attention to those who are considering changing computers.
