Same brand?
Yes: IBM Travelstar, but different models/revs/production dates/ages. Symptoms, results were not identical, as far as I can tell. Worked fine since Yggdrasil, RedHat 5& 6, and SuSE 9.0 through OpenSuSE 11.3.
Then maybe they were old and their time had just arrived.
They were made in early 1980's but each had less than 5K hours running time.
I doubt many disks can tolerate sustained seek activity for long. Motor drivers are often too small to dissipate the heat produced when the disks are called on to seek 100% of the time over periods of hours, let alone tens of minutes. That's what I suspect happened to one, at least. That one failed. The second is still failing.
Unless one is using refrigerator-type cooling system for the computer, or similar, or have the whole computer immersed in the non-conductive liquid (like the Cray for example) then the lowest temperature one can achieve for the innards of a computer - and this means the HDDs as well - is the ambient temperature of the environment in which the computer is operating. 21st Century HDDS are made to work at ~60C when operating and ~65C when idle. Now, if one lives in the tropics then the computer is operating at a pretty high ambient temperature to begin with - and one doesn't hear that anyone living in the tropics has to replace their computer or HDD every month or so :-) . But then, I am probably wrong.....as is normal :-) .
