Hi, thank for helping me

My problem:

So I have a 3TB WS GREEN HDD and windows says it's 1.99 TB when it's actully 3.0 TB, how do I make it recognise the other 1TB? Thank you. Also this isn't my boot drive. And I'm using windows 7 64 bit pro

It needs to be formatted as a GPT drive. It's probably formatted as a MBR drive at the moment. Go into control panel, administrative tools, disk management, and find the 3TB drive listed there. Right click on it, and if the drive only has one partition and is empty, there will be an option to convert the drive to GPT. It HAS to be empty and only have one partition for this option to present itself. If it's not empty, move anything off of it to another drive, make sure there's only one partition listed on it, format the drive, and the option should be there
I hope the 3TB is used as a secondary drive.

the problem is that the drive needs to be initialized as GPT. It sound like the drive is configured as MBR which max size is 2TB.

You will have backup the data on the drive and then do a clean in diskpart and then reinitialize it as GPT and format it.
