Ok guys i need some serious help. My seagate 7200.11 500gb main hdd with both my o's isn't being picked up by my mb so i can't load into os. I sold 1x320gb and 1x500gb so no raid as said in my sig. Im stressing coz the 500gb is full with all my important stuff and im stressing coz just when i remove my raid1 back up i have a problem. Is there anyway i can sort this out without loosing my data.? I tried switching power and sata cables/ports. Help really needed, any assistance is appreciated.
