I had 3 partitions on my 1TB external HDD. I just deleted one, freeing up almost 500GB. Can that 500GB be joined with either of the 2 partitions I now have on the HDD? It appears it won't allow me to do that, only allowing me to create again a new partition from that now empty space. So I'd have to Erase the entire HDD (the 2 existing partitions and the now empty one), and reallocate the space again if I wish to use all memory on the HDD but only have 2 partitions. Is that correct? Thank you.
