I don't really know what the problem is but HD's can get really hot when they are working. Mine are running at 32C(for the bottom one) and 35 (top in the rack) If i'm doing something intesive my temps go up to ~45 but never really much higher. My friends laptop HD gets up past 60C when he is working on his computer. So it is possible you have poor cooling in you're case and it is working normally. But always have backups of anything you want to keep. (i wish i have a dvd burner... My 30CD collection of backups is getting to be alot if I chose to reload it after a failure or format.
