Hi all, I have a stubborn external drive. I can access the files, but get errors sometimes and the permissions are all messed up. It shows as read-only now and I can't change it. In Get Info, after I click the padlock, all the names are grayed out and I can't change anything. I have a backup of the drive, so I tried to just reformat it, but those options are also all grayed out in Disk Utility. Any ideas?
