Okay, I fixed the problem! Here is the solution;
1. After setting up the drive and plugging all the wires back in, fire up your computer.
2. Go to the BIOS setup and select "Integrated Peripherals" or "Peripheral Management", whichever option has the word Peripheral in it.
3. Hunt and find the SATA option and ENABLE it! You may have to open each menu to find where it says SATA, there will be some other letters before SATA but I forgot what they were. (Sorry)
4. After enabling this, save your options and exit BIOS, when Windows starts up it should find your hardware, don't celebrate yet.
5. Right click My Computer and go to Manage, then to Storage on the explorer window and Disk Management.
6. Right click your new drive and choose the partition option, then you should be able to allocate it's size and partition it according to your desires.
7. Make sure you've chosen to format it, just in case.
8. Wait for it to format and when it's done, enjoy your new SATA hard drive as it was meant to be enjoyed :)
This will also be posted on my website. Cuz I'm nice like that.
