During the last three days when booting up the computer on several occasions has failed to detect the two hard drives and of cause displayed the message "HARD DRIVE FAILURE INSERT SYSTEM DISK etc". Shutting down and waiting a few minutes I would get a successful startup. Am I looking at a possible Hard disk failure? The cables were checked for possible displacement but there was no problem there. Also, would the Secondary hard drive not be detected if the Primary one was failing? My system is a P111 667 on a Gigabyte M/B with 640MB SDRam. Any help would be greatly appreciated. Alan Priol In the Blue Mountains of NSW Australia.
