All drives have to be formatted. Wander over here, where I wrote more instructions than you need: http://www.tomshardware.com/forum/265764-32-guide-installed-disk-system
Unasked-for advice: Use the SSD as your boot / system drive. If you can afford the time, do a complete fresh install on it. If not, use good cloning software to clone your OS to it and optimize it for SSD. If you do this, read some of the excellent guides available in sticky threads at the top of the appropriate forums.
