My laptop's original Toshiba 4200 rpm 60GB unit died on me just after 3 years 
of use. I replaced it with a 100GB Hitachi Travelstar 5400rpm unit that works 
at about the same 34-38 C that the Toshiba unit ran at. I think that notebook 
HDDs run warmer due to the lack of ventilation in the HDD compartment and 
this extra heat degrades their lifespan. My desktop has an 80mm intake fan 
blowing over a WD Caviar 250GB and a WD Raptor 74GB unit. The Raptor runs at 
29-31 C and the Caviar was of a bunch with a bad thermal diode (says it's 56 
C.) My notebook is an older model with a "35W" TDP (it's a 45W CPU) Pentium 
4-M and that sits at the lower 60s. If I have a HDD last 3 years in that 
furnace, you might just have gotten a bad HDD.
