My laptop is less than a month old, and it is running F8.
5 Reallocated_Sector_Ct 0x0033 100 100 024 Pre-fail Always - 8589934592000
9 Power_On_Minutes 0x0032 100 100 000 Old_age Always - 167h+02m
12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 89
191 G-Sense_Error_Rate 0x0012 100 100 000 Old_age Always - 2
192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 7
193 Load_Cycle_Count 0x0032 100 100 000 Old_age Always - 5325
The number of reallocated sectors is 000 (forget the high order bits for fujtisu).
The load cycle 5325. This number is correct. When I started to use hdparm in rc.local and in /usr/lib/pm-utils/sleep.d/ (the parameter is lost when returning from hibernation
and suspend mode), it just increments a single unit every time I shut down or suspend.
This is the way it should be in my opinion.
According to this post

(look at the end) the reason is that ext3 commits each 5 seconds, awaking the disk.

I do not believe that the value is exactly the number of load cycles that my
drive already had.
