is my system drive getting too hot?

thanks for all the replies guys. I'm going to do the finger test next... :)

Regarding correlated disk failures, my plan is to force a raid rebuild 
every week to catch faults early. I'm not sure how well that's going to 
work. Also, I've had a lot of problems with WD drives in the past and 
have sworn never to buy them, but in this case, it came with the system 
when I bought it. The WD drive has not showing any errors, but I got the 
following entry in my logs last night...

 WARNING:  Kernel Errors Present

That's a new drive I put in about 3 days ago...

Cheers. Steve.
