Check your hard drive status. Is it old ? Almost dead ?

One thing you should pay attention to is the wealth of your hard drive. You have to keep in mine that a hard drive alive is a hard drive dying. It exists one useful command to analyze your hard drive sensors and give you an idea of its age.

First, try to find your hard drive name. Mine is /dev/sda

This command will display all information about your hard drive

The first bloc of information is about your hard drive name, specification, serial number, etc.


If you hard drive is in good shape, you should see PASSED at this line


The most important and interesting information about your hard drive are in this information table

We’ll look mainly to 4 rows :

  • 9 Power_On_Hours : A value of 19927 hours means 830.3 days -> ~2.3 years. It seems too much and hard drive should be replaced as soon as possible.
  • 12 Power_Cycle_Count : 17 is the number of cycles the hard drive has been fully powered on/off.
  • 193 Load_Cycle_Count : 17 means the hard drive loaded/unloaded 17 cycles into head landing zone position. An excessive value here could lead to a premature death of your hard drive.  The typical lifetime rating for laptop (2.5-in) hard drives is 300,000 to 600,000 load cycles. Some laptop drives are programmed to unload the heads whenever there has not been any activity for about five seconds. Many Linux installations write to the file system a few times a minute in the background. As a result, there may be 100 or more load cycles per hour, and the load cycle rating may be exceeded in less than a year.
  • 194 Temperature_Celsius : Current internal temperature. Your hard drive should never exceed 50°C. So 28°C  is a really good value.


Now you can check by yourself you hard drive status when you receive a new dedicated server.

If you don’t have a new one or at least a lower than a year cycles, you should complain about it as soon as possible.
