These are my computer specs: http://www.cavalryforces.com/upload/files/temp/Report.txt This is the problem: I got an old hard drive from a friend and I switched around the master/slave settings on all of my drives. My 120GB primary and the 6GB backup drive were recognized and worked fine. IDE1 and IDE2 are the hard drives and IDE3 and IDE4 are the optical drives. The optical drives have power because I can open and close them but they aren't recognized. I flashed my BIOS on my mobo to the latest version (Soyo P4I875P Dragon 2 Platinum http://www.soyousa.com) and updated my chipset drivers (Intel 875P http://support.intel.com/support/chipsets/index.htm) I've tried the optimized and fail safe defaults in my bios as well as tweaking different options. PLEASE HELP!!!!!!!
