Merging Partitions in Mac

[cornopaez]

So, I have an extra partition in my external HD that I don't need anymore and I was wondering if there's a way to merge two partitions (one completely empty and other with my Time Machine stuff) without having to reformat the whole drive just to have it as I want to.

Is there really a way?

The best (and fast and safe) solution is reformat the disk. Of course, make a backup earlier (full).

If you really want to merge, check this page and this.
