I'm trying to create a dev drive in Windows 11 on some unallocated space, however when I try I get this error message:

Unable to format volume. Error: Cannot perform the requested operation when the drive is read-only (8)

The unallocated space changes to 'RAW' in disk managment. The drive itself which is my C: drive, disk 0 is not read-only and doesn't appear as such in disk management.
