ATV SILVER KODI EDITION

First attempt to make install flash drive worked well , Now when I attempt to make a install flash drive I get a ERROR ( hdutil.exe ) not working . I close error and it continues to make flash drive and at end says flash drive is safe to remove . However flash drives do not not work to install on ATV silver .
I attached a picture of error
