How to fix Media Creation Tool error 0x80070005 - 0xA001B in Windows?

The error code 0x80070005 – 0xA001B is one of the common issues that users encounter when using the Media Creation Tool to create a bootable USB drive for Windows installation. The error usually occurs during the process of writing the installation files to the USB device, which suddenly stops and doesn't allow the process to continue with the creation of the installation media. Users have reported that this error usually occurs right after selecting the USB drive as the destination for the installation files, only to be met with the error message partway through the process.

The main causes of the 0x80070005 – 0xA001B error include:

• File system incompatibility
  The USB drive may be formatted in the FAT32 file system, which has a maximum limit on file size at 4GB. If the installation files are larger than this, it can cause failure.
• Insufficient permissions
  If the Media Creation Tool is run without administrative privileges, it may not have access to all parts, hence the error.
• Antivirus interference
  The Security software can prevent some of the operations done by the media creation tool, which prematurely terminates the process.
• Corrupted USB drive
  There are occasions when this error is raised due to the USB itself, possibly because of some corrupted sectors or an incorrect partition scheme.

One of the prerequisites for avoiding the 0x80070005 – 0xA001B error is that the USB must be formatted on a compatible file system NTFS, which also allows larger files. Additionally, running the Media Creation Tool with administrative rights can help overcome permission-related obstacles.

Temporarily disabling antivirus software during the creation process may prevent unnecessary interference. If the 0x80070005 – 0xA001B error persists, consider using alternative tools like Rufus to create the bootable USB drive, as some users have found success with this method.
