Smartmontools load_cycle_count
By SVAKSHA on 2010 December 17 [Friday], 17:21:00 - HARDWARE - Permalink
Dear Lazyweb,
If you have installed "smartmontools" on your laptop on Ubuntu-Lucid, has it been behaving erratically after the last update about a week ago?
me@ubuntu:~$ sudo smartctl -s on -a /dev/sda
smartctl version 5.38 [i686-pc-linux-gnu] Copyright (C) 2002-8 Bruce
AllenAs you can see here, there is no LCC for desktop server
hard-disks and its especially meant for laptop HDD, where I'm interested in
limiting the Load_Cycle_Count (LCC) to increment only with
each boot cycle. Yeah, it has inherent
risks, but...

- 227825However, since (the lucid update) last week, running 'smartctl' has not worked its magic since the count has incremented from
227684 to 227825
within an hour. I've been randomly checking it every other hour or so to find
the LCC racing away.Is this a sign that the HDD is dying? Is this a hardware issue or has the code-base changed to require a rebuild? What am I missing here?
