Recently I noticed that one of the hard drives in my 4-year-old Dell Precision 470 was turning up too many errors. I downloaded a couple of SMART monitoring programs and discovered that both drives - Maxtor Diamondmaxes - were running hot. One was 45-55C, the other 50-60C. The latter was showing many bad blocks. Evidently, it was on the way out.
So I ordered this "vanilla" hard drive from Amazon, and when it arrived a few days later I found I had a Hitachi Deskstar. (It's important to note that your mileage may vary: all you are promised is a good quality 500GB HDD, but in practice it will be a "name" brand). Knowing the "Deathstar's" unenviable reputation, I was concerned, but I fitted it. That took about 10 minutes, and I immediately saw the Deskstar was stable at about 35C, with the remaining Diamondmax now at about 45C. Both are well within acceptable temperature limits, and everything is working smoothly. The Deskstar is very roomy at 500GB, and performs better than the old drive - which was a pretty good spec when I bought it in 2005. All in all, a very good deal for the money.
