Old computer N360 backup set on USB Seagate drive from older computer. Have a new N360 set saved on the drive from the current computer and need to remove the older set which no longer is needed. Trying to delete the directory for the older set gives an administrator permissions error. I click on the button that should give the permission and it still errors out. All listed administrators on the machine have full permissions to the drive.) Is there a solution for this? (The older computer had its motherboard replaced and is running Windows 11 from scratch, so administrative ID on machine changed.)
