Try rightclicking My Computer and choosing Manage.

Look under Disk Management

Do you see an unallocated disk?

engineroom,

I would first check to see if it appears in BIOS.  BIOS information will show as your computer starts before Windows starts to load.  Do you see the BIOS information?  Does the drive appear in the list?  If it goes to quick then try to choose the option to enter Setup that will appear at the same time.  Most often this is done by hitting the F1 or Delete key on your keyboard.

how are the drives connected? IDE  SCSI   SATA?
You can check All the Drives available to your system :-

1. Start > Run >  compmgmt.msc
2. Click "Disk Management" under Storage Catogery
3. If your HDD is Detected Correctly by System's BIOS, You can see all the available drives there.

If only one HDD is shown at above location.

Possible Causes :-
1. HDD was not detected by BIOS (Check HDD at BIOS).
2. There may be some Corruption of Patition Table. (In this Cond. you can see it using above method)

Download Tool :- http://65.24.134.81/KipSolutions/Downloads/aida32pe_393.zip
Using this tool you can check any hardware details of your system.

To check HDD Select Storage in Tree View then Click "Physical Drives".

Yes, i do see the disk there, but it isn't showing up on the desktop.

@b0lsc0tt
I'll give that a shot

@Jay_Jay70
SATA

@sunilcomputer
I'll try that as well.

Great!
Now rightclick that unallocated disk and make a new partition. Once it's assigned a drive letter it will show up under My Computer.

Okay, before i do that, i got this wizard... welcome to the Write signature and Upgrade Disk Wizard.. Says something about software based Raid. Drives can be mirrored as well as striped or spanned across disks. What do you think?

Commented:
are you wanting to setup a software RAID (mirror) if so then follow the wizard if not, then dont bother. you dont want to span or striped you just want the disk as a data disk i take it?
Commented:
Don't accept the upgrade options (raid spanned/striped/mirrored), but do accept the creation of disk signature for the new disk. Once you've done that you'll back back at the main window.

The drive will have a black bar across the top. Rightclick the bar and create a partition. Use Primary partion, Accept maximum disk space, choose a drive letter, format in NTFS w/ quick format checked, hit finish

That should be it

@jay
what are the benefits of striped/span?

CERTIFIED EXPERT

Commented:
they are in regards to RAID, just means that your data is spread over disks, wouldnt bother with windows arrays... more a hardware RAID benefit. Its a redundancy tool   if one disk fails the others can keep going   usually implemented at RAID 5 and above
