    I want to copy a 2.5TB HD to a 2TB HD. The 2.5 TB is not full and should be less than 2TB.Does the 'size' being copied make any difference?

    The make sure you clear your Internet cache and delete old email attchments! Plus you could take out the okd hard drive and get an external caddy and put that older drive into it.

    It should work just fine, as long as the 2.5 TB is less than 2 TB full.
    I think you misunderstood the OP's question...

    It will work fine depending on what you use to make the copy. Something like CCC will copy that over just fine. But if you try to copy (restore) with Disk Utility it won't work since the destination volume needs to be as large or larger than the source. You can use DU to shrink the source down below 2TB then do the copy with DU if you like.

    I'm using CCC to copy the most up-to-date HD to the new HD, but it won't then boot(newer one).
    Trimming some music files off to reduce any size problems, it starts to boot then cursor disappears.
    Don't know what I'm missing....

    CCC should do the trick. Is the new drive formatted to Mac OS Extended (Journaled) in Disk Utility?

    No I didn't! I gave the OP three suggestions.
