Windows wont find new HDD, helpy newby!

[Logic Zero]

Yep, iv got me a WD2500ks and a 74gb raptor, XP is on the raptor but i want the 2500ks for files.

It booted fine with the raptor in, and i when i plugged the 2500ks into the mobo it recognized it in the bios. But when it comes to windows it only detects C: (the raptor)

I know im a newb, id appreciate it if someone told me how to get windows to show the 2500ks

Thanks a tonne dudes

You need to go into computer management, disc tools, then activate the drive, then partition and format.
