I can not access all the space on one of my new HDD's

[Acidic07]

Hey there everyone, I recently installed another hard drive in my pc, (a total of 3) the "new" drive came out of another pc I had around the house. It is a Sea gate 1tb drive, file system NTFS. I would like to be able to access the rest of the space on the disk. Any information you have would be appreciated. Thank you in advance. If you need anything else, just ask, i'll do my best. System specs are listed below.

System specs: AMD FX 6300 cpu, Asus M5A97 R2.0 Mother board, GTX 970 g1 edition graphics card, 16GB ddr3 ram, Corsair cx750m 750 watt psu 80+ bronze, Cooler Master Hyper 212 evo cpu cooler.

What space seems to be missing?

Can you post a screencap of your Disk Management window, with this new drive identified?

I do yes, thank you http://postimg.org/image/80tlx6jsr/

So we're talking about Disk 0, right?
The 1TB, with 913GB Unallocated?

So, what options does it give you if you right click on that Unallocated space?

I actually just figured it out, seems silly but all I needed to do was allocate the space, it reads the full drive now. Thank you so much for your help, I didn't intent to waste your time

No problem. Not a waste of time.
Sometime in the near future, someone else will have a similar issue and come across this thread. Seeing this, they will probably figure it out for their system.
