Running smartctl -a /dev/disk0 I get:
193 Load_Cycle_Count 0x0032 097 097 000 Old_age Always - 66403
According to the original article he was at 56000 load cycles! I'm at 66403! Yikes!
I bought the machine in June of this year!
Upon further reading it looks like this might not be an operating system issue.
The following things might instead cause aggressive power management settings :
your (laptop) harddrive firmware might have aggressive power management defaults (operating system independent)
your (laptop) BIOS might set your harddrive to use aggressive power management (operating system independent)
you might have enabled laptop-mode in /etc/default/acpi-support (disabled by default) which will set your harddrive to use aggressive power management
Anyway, I don't think I'm going to really get worried about this any further.
