    Hi Guys,

    My Internal drive is almost full, and am going to buy a 1TB WD My book to use as my new Time Machine drive whilst using the old 500GB WD My Book as extra storage.

    My question is, if after a while the internal drive fails (which it has in the past) what is the correct procedure to restore from the TM backup once the new internal drive is in place? I ask this as the TM backup will be copying files from both the internal and external drives. Is it smart enough to ignore backing up to the external drive because the data is still there, or will the external backup need to be disconnected whilst I restore from TM. Or, is there something else that I've not thought of??

    Thanks for your time!

    Though I don't know for sure, as I've never had this situation before, I would guess that Time Machine would be smart enough to only restore the internal drive's backup data, should it fail and need replacement.

    If the external drive also needs to be restored, that can be done separately, from the Time Machine interface.

    I have a similar setup. I have a WD 1TB Drive that is partitioned into two 500GB sections.

    I use one section for back up and one section for file space.

    TimeMachine does not allow me to back up the partition that is used as file space.

    I dont know if that helps, it may be because it is a partition.

    P.S. The WD Hard Drives are ace.
