Solved: 3 SATA drives on same MB?

OK guys, Im about to do a windows 7 install, but I am changing this computer.
I currently have a Maxtor 120Gig drive with windows xp installed. Sata
Also, 2 CD/DVD drives, one is a burner One IDE the other SATA
1, WD 500 gig HD, for storage.

And now 1 TB Toshiba hard drive. that I am adding also, SATA.

Now what I want to do is take the stuff on the 500, and put it on the 1TB,
Then format the 500 and us it for windows 7 install.

Here is my sistuation.

I have installed all 3 drives.

In MY COMPUTER, the 3rd HD does not show up.
But in My computer, hard ware manager, it does.
It has NOT been formated yet..


So how do I format it, so that windows XP sees it in My computer?

Thanks.
