drive F:\ ----> C:\ ??? ok a friend's computer is buggered. When installing the OS (XP), the installed forgot a rule in teching. He forgot to disconnect the IDE Zip drive from the computer. SOOOOOOO The OS recognized the Zip drive as drice C:\ and the actual local disk with the OS on it as drive F:\. My question is: can I change the local hard drive with the OS on it into drive C:\ without formatting and reinstalling (of course with the Zip disconnected in that case)?
