On Startup the USB External Drive is in Read Only mode
On Mojave my external USB drive, formatted as MAC OS Extended Journaled, always boots from startup as read only. However, if I use the disk utility and unmount and then mount it, then it becomes read write. How can I stop the disk being read only mode on startup? I realize it's minor and I have a workaround, it just backup always starts and gives me an error, which I then have to use the utility and then tell backup to go again.
