In reply to Eric,
I was using a program called Speccy and it showed heaps of information about everything in your computer, inc hard drives. It showed S.M.A.R.T. info.
you can download it here:

Jeff Atwood is quite right you shouldnât play chicken with your data. Thatâs what BACKUPS are for. Itâs far smarter to have your HDDs at 45 degrees C and regularly backup then it is to have your HDD at 20 degrees C and never or rarely backup. Particularly if your data is your professional work. In other words, the most important thing you should do is to keep backups of important data NOT to monitor HDDs temperatures.
Incidentally, anecdotal claims like âMy HDD died at it was 50 degrees Câ or even âIâve usually kept my HDDs at 30 degrees C but this one case I let it reach 50 degrees C and it diedâ are basically useless in determing quantitative failure statistics like Google provided.
P.S. And no, RAID isnât a backup. If you think it is, you probably shouldnât be working professionally in the computing field.
