Adding another hard drive ? - conecting hard drive to tv

I would like a hard disk with the information they need an old computer (eg) Can someone explain later, a custom boot, as you do, is simply a question of the connection made the band. They are both XP Home. and how the computer recognizes the drive? b is just another drive letter extra ........ I hope I can do no wrong! We thank you, if someone can help
