External Hard Drive not showing up on Macbook
My External Hard Drive with my Time Machine Backups on it are no longer showing up on my Macbook. The disk shows up on disk utility. Also when I boot into Recovery Mode and click on restore from Time Machine Backups my backups are listed.
I've tried to erase the disk and start fresh, but Disk Utility will not unmount the disk.
Macbook Pro 15"
