I just got my new machine set up last night, but my second hard drive (SATA) shows up as F: in WinXP. It's a picky thing but I want to change it, so when I went into disk management, it was listed as a system drive (C: is listed as the boot drive) and wouldn't let me change the letter. Windows and everything to do with it (documents and settings, program files, windows) is on C:, when I went to change the other drive, there was nothing on it. Is there something I can do to change it?
