    Unable to backup
    Hi all,
    I have a MBP. I use a Seagate Free Agent, Goflex external disk for backup. Recently, I am unable to backup and it says "Time Machine could not backup. The backup disk is not available." Normally I just click Back Up Now and it works. Not now! Thanks for your advice.

    Specs:
    Mid-2012 MBP (16GB, 1TB HD), Monoprice 24-inch second monitor, iPhone 5s 32GB, iPad Air 2 64GB
    If you still have everything on your boot drive that you wanted to keep backed up, I would suggest reformatting the Seagate Drive (do NOT use any included Seagate software, just Disk Utility) and doing a fresh new backup.

    Specs:
    Imac 27" Retina 5K, 512GB Flash Storage, 3.3Ghz, 16GB memory, OS X.11.5.
    Connect up the external - go into Disk utility, select the drive (Highlight), go into Erase and select mac OS Extended (Journaled) and proceed. Then use Time Machine or cloning software such as SuperDuper or CarbonCopyCloner. Cloning will make the external drive bootable.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
