    is ubuntu telling me my hard drive is going bad?

    I read about using the smartmontools to monitor the health of my hard disk, and when I ran
    Code:
    sudo smartctl -a /dev/sda
    I get this output:

    Code:

    According to the link, which was referring to hp pavilion laptops, same type as the computer I'm using, the Load Cycles Count should be around 200 for a new drive, and slowly decrease as the health of the drive goes bad. Am I reading these results wrong? My load cycles count is around 70! and this computer almost exactly 1 year old. Is my hard drive already "getting old" and going to die on me soon, or am I not reading the test properly? Thanks! If anyone can tell me any more general information from these results that I should know, that'd be great too.

    EDIT: Here's the link I'm talking about, too:

    Smart values can be hard to read. VALUE is supposed to be the current value(different models vary on how this is calculated). WORST is the lowest seen by the disk so far. THRESH is the value that when reached in a pre-fail attribute will trigger a "failed SMART status". WHEN_FAILED is self explanatory. You only have one fail sometime in the past with
    Airflow_Temperature_Cel. The value during the test was 54C. Most of the time you want to read the RAW_VALUE column. It usually represents the actual reading at the time of the test. The most important value to watch IMHO is the Reallocated_Sector_Ct. It counts how many sectors the
    disk was unable to read and had to replace. Don't freak out, yours looks fine

    You can install gsmartcontrol. It is a GUI frontend for smartmontools. It has tooltips that will explain what most things are when you hover over them. http://download.opensuse.org/reposit...+nmu1_i386.deb
