A few months after I got my computer it started giving me an error saying: PRI MASTER HDD STATUS BAD: BACKUP AND REPLACE. (WD 80gb) I knew my drive was supposed to fail but I just kept using it and figured I would replace it when it did fail. I used it for ten months, getting the same error everytime it booted, and I had no other problems; when I tried to find a specific error code or something it said the drive was OK but still gave me a generic error. Two weeks ago it started not recognizing the drive and freezing after it had been running for about ten minutes; so I figured the drive had finally failed and I replaced it with a similar WD Caviar 80gb. While I was installing the OS on the new drive, all of the sudden the new drive dissappeared just like the old one used to. I rebooted, and got the same SMART error too. I heard somewhere that errors could be caused by faulty cables or something, so I replaced the IDE cable to the HDD. Now it can't find my optical drives. Whats goin on? Any ideas? I don't want to mess with it again until I know whats wrong.
