WARNING:

Fiddling around with hdparm might stop the unload/load cycles but can also dramatically increases HD Temp - at least here on my Compaq Evo600N:

192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 12
193 Load_Cycle_Count 0x0032 094 094 000 Old_age Always - 67387
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 50 (Lifetime Min/Max 16/50)

-->we have winter, the laptop is being used as a web server, low load, in a very cold room (14 degress Celsius!!) The fan is going on constantly to cool down the HD.
I took the -B 200 value, which works fine for my HP NX6325 - but NOT for this machine. I have to check if this is connected with laptop-mode - although I am on cable, it seems to be activated during boot up.

So careful with modifying APM values with hdparm.....

I think this bug does not get more importance until Mark Shuttleworth notebook dies from it :-((((((
