i have had my two westen digital hard drives for a year now and i did have them setup in raid but this failed so i went back to one storing all my music and pictures and one with my os on!! for some reason after playing with my overclock they no longer show up in bios and therefore wont boot, the funny thing is my other two hard drives do show up, i have changed all the cables reset bios and no luck i dont know why they have stoped! why would they fail at the same time? and i did buy them from new so has anyone ever returned a WD hard drive will they have a go about all my 90g of downloaded music? if you can help me out you i will owe you months of downloading!!as i dont have my music backup as its to large on my pictures!!
