@jokeman:
I don't know, but overall, that's reasonable. A laptop usually spends
at most about 1/3 of its life on battery, and it's good for the disk to
stay parked while on battery if possible (it helps protect against
impacts). Keep an eye on it and make sure that it isn't incrementing
while on AC, and the parks while on battery are few enough that it
shouldn't be a problem. I.e., no increase while on AC, ~17/hr on
battery should give you ~10 years of usable hd time, even accounting for
the load cycles that are already used.
