HFSExplorer doesn't see it, nor does HFS+ (trial version). I can plug it into my MBP and everything is there. I have about 800 GB on there that I would like to get off, and my MBP HD is only 750 GB. Any advice or ideas? Perhaps something I am doing wrong?
Win 7 Pro fully updated.

Plug it into your MBP, and move it across the network. Preferably wired.

I can do that. I was hoping I was just being dense and missed a setting or something.

Your external may need more power from a USB port than your Win device offers. Got a power adapter for it?
It's also possible the external has been converted to a Core Storage volume.

This. The Yosemite installer will do this automatically in certain circumstances (basically the startup drive on any Mac from 2011 and later, plus a few more), and even older OSes do so sometimes (enabling FileVault 2 is the easiest way to trigger that).
Also...what partition map was used?

The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

It's a powered device. Seagate 1.5 TB drive.

I did not initially format the drive, so I am unsure. Is there a way to check?

Disk Utility is your friend. Select the drive volume, check the info at the bottom of the DU window. Then do the same with the drive hardware icon. With an internal drive, you'll get all the info. With an external, it will depend on how much info the interface chip passes along.
About detecting a Core Storage volume, you may need some Terminal kung-fu. I don't have that command memorized, sorry.

On the terminal, type
There are other ways, but this one does not require root, and it tells you in plain English if it does NOT detect any CoreStorage volumes.
A slight variation on this command, namely
will also tell you the partition scheme of each attached drive.
