Did you run diskmgmt.msc?

It now shows 800GB unallocated and displays as 1.99TB. Where's my third terabyte???

I believe mine is this one: http://www.vantecusa.com/en/product/view_detail/212
 
How do I get the remaining terabyte back????? What do you mean by "as it increases", exactly?

What type of Partition did you create?
You need a GPT Partition to use all of the drive.
Are you also using UEFI Boot in your Bios?

Partition style is MBR. How do I go about creating a GPT partition? Talk me through it when you can.

Delete by using Diskpart from a CMD or DOS Prompt
Type DISKPART and press Enter
DISKPART>list disk
DISKPART> list disk
  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---  
Disk 0    Online          931 GB      0 B  
Disk 1    Online          232 GB  1024 KB  
Disk 2    Online          119 GB      0 B        *  
Disk 3    Online           14 GB      0 B
 
The Disk you want to clear will be sown to you.
Say that it is Disk 3
Now you would Type
 
DISKPART> select disk 3
Disk 3 is now the selected disk.
DISKPART>Clean
You cannot Stop the Command Clean Once your Press Enter
DISKPART>exit
exit
 
 
Now run diskmgmt.msc and create a GPT partition

First time I ran into a partition and enclosure problem.
 
Your solution worked beautifully. Thanks again for all your help.
 
As for the enclosures, I have 4 of them, and the 3TB and 500GB HD's don't work in one of the enclosures for some reason. Bu the 2TB and 320GB HD's do. Strange.

Hello.. I apologize for resurrecting this thread, but I'm trying to get my NST-360UFS-BK to recognize a wd 1.5TB mybook. It's spinning the drive up, but nothing is shown via usb 2.0 or esata.. disk management shows nothing, this pc shows nothing.. I'm trying this on 2 different laptops both running windows 10.. on 1 of the laptops, when I try the usb 2.0 route, the device manager asks to install a driver for the new device and comes up as initio combo device class.. I purchased the enclosure new a few years back and when i didnt have any luck on my old machine running windows 7, I gave it a rest for awhile.. and the problem is, or could be, i dont remember there being any driver disc included in the packaging.. however, i read online that it should contain a mini cdrom, and i DEFINITELY never saw that. Needless to say, I'm at a total loss and my next logical step is to find those driver files, and everything i find online gets flagged for malware/viruses. Is there anyway you could possibly sort me out with the drivers so I can scratch that off my list of things tried and failed (but hopefully it would work). Seeing as Vantac no longer carries this product, Im basically out of options as far as proper drivers go unless I can find a good samaritan. Im looking forward to your reply, and either way.. thank you for your time.
