Did a Disk Utility open to try to mount an external drive and low and behold the internal 1TB drive in the 27" iMac was in red highlight - saying: This drive has a hardware problem that can't be repaired. S.M.A.R.T. Status: Failing What is the MTBF (Mean Time Between Failure) on these drives installed? I do use this iMac for watching TV, using EyeTV with a 20GB buffer, but would have thought the drive would be able to handle it. Its not on 24/7, about 4-5 hours a day on average, then movies on VLC for another 2-3 hours. I do have care so will be covered but what's your thoughts on EyeTV on this machine, too much for the drive to handle?? or should be fine and not an issue.
