Over 2TB has to be partitioned as GPT, not MBR. MBR only supports a 
drive of 2TB max.

Older systems don't support GPT, *but* if your partition software knows 
GPT, then it can chop up the disk into under-2TB partitions which the
non-GPT-capable system can then see. (I've done this with 3TB drives so 
an old quad core could see them.)

Probably the partition software is looking at BIOS support and saying 
nope, no can do. And if you do manage to merge it, you may lose access 
to the entire disk, at least on this system (it should still be readable 
on a newer BIOS with GPT support).

So I would most strongly recommend that you leave well enough alone, and 
just use the secondary partitions as Another Big Folder.

BTW this is why I just bought a 2TB data drive even tho I have a stack 
of 3TB drives -- the 2TB will be readable on anything from a late P4 on 
up, while the 3TB have to be chopped up into smaller partitions before 
they can be read on the older systems.

I no longer mount drives internally; now I use iStarUSA hotswap bays. SO 
much easier, especially since multiboot no longer works right with 
Windows (and is risky now that it rewrites the boot sector when you 
change OSs, rather than just pointing at a different one), and was 
always risky if you cross species lines and multiboot Windows and linux. 
Now I just swap the boot drive, and every OS uses the same data drive
(formatted NTFS).
