My drive is the Seagate ST31000528ASQ 1TB. It has made little noise. I only hear it at startup and it is not loud, more than acceptable. Thought I was a lucky one! NOW, having said that, I looked for a drive utility. I downloaded the trial version of Smartutility from: http://www.volitans-software.com/index.php I run a test and it shows my HD failing! Best I can tell is that the temp on line 190 has ran high as it is redlined 58C with a threshold of 45. As I write, it shows current temp of 43C. Under type heading there are lines marked pre-fail on spin up time, reallocated sector count, seek error rate, spin retry count. All others under type are tagged old age. Believe this also shows this hd has 25 hours on it, I have not ran it that long. Looking for comparisons folks. Could heat be causing our problems??? I have been a life long WD user with zero failures. I dropped one one time on a concrete floor and it still worked after than with just a couple bad sectors, my fault. First computers at work years ago had Seagate drives, they did not last. I have i5 4850 27". All is working, but now I am miffed about my first Mac! Has anyone else tried this utility and if so, how about results? I suppose I will pack it up and call for shipping papers dang it!. Any input appreciated.
