    I'm new to Time Machine. I have purchased a new MyBook 4TB, set it up as Apple instructs to use as a time machine and have TRIED to just target one drive for it to back up (which is a 2TB drive almost half full) when the Time Machine goes through its attempt cycle is comes back with an error saying that I have exceeded its compacity by trying to add over 5TB when I only have the half full 2TB selected. Any advice?

    Just to confirm, your Mac has a 2 TB drive, filled at around 1 TB? You have formatted the backup disk as Mac OS Extended (Journaled) with partitioning scheme GPT/GUID Partition Map?

    I have this unit and have had nothing but trouble with it....I suggest you get a wired self-contained hard drive and use it.

    Run Diskutilty.. This may help. I have seen this before where the OS thinks it's using more space than actual.
