I am trying to reformat the external disk I am using for backup on Time Machine, but Disk Utility doesnt see it. It shows up in Finder as a shared disk. I am using OSX 10.11.6. Thanks.
MacBook Pro (15-inch Mid 2010), OS X Mountain Lion (10.8.5), Install.app
The Disk Utility isn't supposed to see network drives.
If it's an USB drive, connect it to your computer.
If it's an Ethernet or wireless drive, use a utility specifically designed for it.

Disk Utility cannot be used on a "shared" or "network" drive.
To reformat the drive, you will need to first connect it directly to your Mac using USB, FireWire or Thunderbolt connection. Then, Disk Utility will be able to "see" the drive so that you can reformat it.
Once that is done, you can connect the drive back at its original location.
Thanks Bob.
