On my current laptop I have:
193 Load_Cycle_Count 0x0032 001 001 000 Old_age Always - 2115831
This is much higher! I haven't noticed any sign of failure yet.
On another laptop, I had:
193 Load_Cycle_Count 0x0012 001 001 000 Old_age Always - 3759880
before a fatal failure.
Perhaps you can ignore what you have found on the web.

On my current laptop, I had to set
# VL: apm_battery was 127 by default, but the -S option (spindown_time)
# doesn't seem to work, and since the drive is used very often, let's
# forbid spin-down by setting apm_battery to 128 (any value between 128
# and 254 should be OK). See:
# http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684241
# http://askubuntu.com/questions/137544/how-to-change-harddrive-spindown-time
apm_battery = 128
in /etc/hdparm.conf several months ago. Since then, bug 684241 has
been fixed, so that this may no longer be necessary.
