Comment 346 for bug 59695

 Luca Cerutti has a point, which may be relevant to finding the cause: Windows also has this problem in some cases, to wit, my Acer Travelmate 4010 laptop (Windows XP, with Hitachi IC25N060ATMR04 drive) has been getting increasingly more Load_Cycles per hour. The average over the last 250 hours was 25 per hour (Load_Cycle_Count/Power_On_Hours). So the problem extends beyond Ubuntu, and Linux. If my wife didn't need it for her job, I'd run a live Ubunto on it and see what happens under Linux. Seems like more multi-OS data on the same machine needs to be collected to get some controlled data.
