hot hard drive = dying hard drive?

[Mr Mister]

Ive got 4 hard drives in my system, in the front of a lian li pc65 with the 2 80mm fans blowing across them at medium fan speed. 3 drives are around 35C mark yet one is at 42C and it isnt being worked at all as it has no data on it. Is this a sign of it dying? Whats the best program to test for bad sectors etc? Its a Western Digital HDD btw.

ok thanks for the replies guys, i did the smart test in speedfan and the hottest one is 98% Fitness, so no problems there. I suppose 42C is not that hot anyway for a hdd.
