While WD could no doubt have tried harder to make their disks "fail
safe", the real issue is likely with the chassis and environment you
have the disk installed in.

Older Seagate Cheetah's, for example, required relatively enormous
amounts of air flow to maintain proper heat dissipation in an average
office or home environment (on the order of 120CFM air-flow across each
drive, IIRC).

WD should probably have published much more detailed cooling
requirements in their manuals as well, though that would only allow you
to point the finger more accurately at the system integrator.
