i have a motherboard which is kk266 r, i know it is capable of raid, (im not sure what that is exactly) but i do know that there seems to be 4 ide slots on the motherboard, now i want to add a 3rd hard disc in my computer, i was wondering if anyone knows if i can add the 3rd hard disc in to 1 of the raid type slots, or will it not work. (i think raid is to do with mirroring hard disc to keep a back up and also splitting the task between to hard disc to do a job,) but if anyone knows if i can add a third hard disc in the yellow raid slot will it work as a 3rd hard disc, i really need someones help and advice, thanks for you time.
