Just got done putting together a new computer with a EVGA 680i Mobo with 2 150 Gig WD Raptors in Raid 0. Every thing went fine, formatting my hard drive(s) and installing Windows XP Professional. After it was done and a reboot, I looked at the directory, windows had labeled my Raid array as the "F "drive instead of the normal "C" drive. Any one know why? These are the only hard drives installed in my computer. Everything works fine but before spending time installing programs I would like to know if I should leave it this way or do a reformat?
