3TB WD Ext HDD only seen as 746GB?

I have a Linksys E4200 router and connected a new WD Elements 3TB external HDD to. The router reads that it has the full 3TB so I thought everything was fine and dandy. It was until a year or so later that when I finally filled it to 746GB, I was already full! I tried hooking it up to my desktop and it would do the same thing to me.

I've searched all over for a solution and I tried several things without much success. I've updated the firmware of my router, I've updated my desktop's Intel chipset and mobo bios. I looked up the hard drive in Disk Management and the weird thing is it shows the drive as NTFS 746.52GB (0% free) but in the lower half of Disk Management, it shows the drive as having one partition that is 2794.52GB, with all space allocated.

I'm so lost on this one. Ideally I would move all 746GB to my desktop, reformat the external, and move it back. However...I don't have the space, which was why I have a 3TB in the first place! Please advise :)

to clarify the drive shows up twice in the Disk Manager?

when you connected the drive to the Linksys did you have to do a setup?
Does the router say anything about size limitation?

In disk manager, there's the upper portion that lists the drives and the lower portion that shows each drive's partitions. The upper portion listed my 3TB as 746GB while the lower portion showing the drive closer to 3TB.

I don't remember having to setup my external with the router. The router's firmware at the time might have been unable to read all 3TB, which I was unaware of. I've since updated its firmware, which specifically fixes the router to read all 3TB.
