Guys,

I spent a bunch of time setting up smartd on my system at work last week 
and now I'm getting nightly e-mails regarding my disk drives. (the 
latest one is cut and pasted into the e-mail.) notice sda, and the 
temperatures over 100. Is this something I need to worry about? The sda 
is a WD drive, while all the other drives are segate.
