    I have a 320GB internal drive and 1TB (MyBook) external drive. I recently bought a second 1TB external drive (MyVault)to use with Time Machine. I have removed the exclusion of MyBook so that Time Machine backs it up but so far it has refused to do so. It is happily backing up the internal drive. I have looked in the Mac OSX Leopard Missing Manual but still have no clue as to what I am missing. The initial setup (and backup) did not include MyBook until I discovered that I would have to remove it from the exclusions.
    Any help in sorting this out would be appreciated. I am new to the Mac and this is really testing me.

    Sounds like the non-TM external drive is not formatted in HFS+ format. This is needed for TM to back it up. If you have files on it, move them out, format in HFS+ and move the files back (and of course, remove it from the exclude list of TM).

    [Of course, only the writes by Leopard machines (TM-aware) will be reliably backed up. For details, see the Ars Technica article on Time Machine and fsevents link from there.]
