Power_On_Hours = 331
Load_Cycle_Count = 17780
So that makes it 53.71 Cycles / hr. You can now calculate how long your hard disk will last by taking into consideration the number of hours you use it daily.

Also, check that airflow temperature. its 59 in your case.

A quote from this page: http://ata.wiki.kernel.org/index.php...ds_under_Linux

"Note that modern laptop drives are supposed to unload frequently to save power. Unless the unloading is excessive, disabling powersaving is not a good idea. It seems that most modern drives are rated for 600,000 load/unload cycles which translates to about two years of uptime at 35 unloads per hour. Even when assuming continuous 12 hours of usage everyday, this means the drive will only reach its rated load/unload cycle limit after four years and shouldn't be considered malfunctioning. Please only report cases where the expected uptime is significantly lower than two years.
"

Here is the explanation of the S.M.A.R.T Parameters
