Can't Install HDD, HELP!

Hi there, I have just set up my new system. I installed all my stuff on an SSD, and when I plug my HDD in, it acknowledges it but doesn't let me use it.

Also, I am using a 24'' monitor, and there is a black bezel (black pixels) surrounding my mon. I cant move my mouse into the pixels but I know the mon isnt defective because it works fine on my old comp.

Specs are
G1SNIPER2
2500k (stock)
XFX 7970
OCZ Octane 120GB ( The SSD)
Hitachi 640GB HDD

I am running Win 7 Home Prem btw.

If this is a new harddrive, you have to initialize, partition, and format it first. See this: http://www.tomshardware.com/forum/forum-32.html .

If the drive has data that you want to access, let us know; that's a different question.

how do i initialize partition and format? Your guide uses XP...

please help, anyone D:

Does the drive show up in "computer" next to the other one?
If so, You simply right click it, select format and then not change any setting (other than perhaps give it a name. If there are anything on the drive, this will delete it though.
This is assuming you only want a single "partion"

start > type in computer management > hit enter

on the left pane under storage select Disk Management

find your hard drive, right click and pick the options (format, etc)
