How to check Hard drive health?

One week back, my friend got hdd failure and he lost his some very important data. So I thought of writing this article.

Hard disk failure can happen without giving any warning signs. So it is very important to check hard drive for errors once in a while. Which will give the idea replacement of hard drive is necessary or not.

So now here are some things you can do for testing health of hard drive.

1. Error checking of Hard Drive :

In windows  there is a utility called Chkdsk.exe which can check your hard disk for any bad sectors. There are two ways in which you can check the disk errors first is run Chkdsk from the command line or second is right click drive you want to examine then go to Properties -> Tools -> Check Now button under error checking. Also in case of linux you can run commands like #/sbin/fsck and #/sbin/e2fsck to check the disk errors.

2.Know your hard drive :

It is very important to know some of the facts about hard drive such as drive version, ideal temperature and bad sectors in the hard drive if present. There is one tool I would like to suggest is Stellar Smart. Stellar smart is the utility which acts as early warning system for your hard disk and which is based on on Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T). The hard disk's integrated controller works with various sensors to monitor various aspects of the drive's / disk's performance and determines from this information if the disk is behaving normally or not.
Bad Sectors !!!
By learning how much bad sectors are there on hard disk then you can decide about its usability and replacement! Stellar Smart's scan hard disk feature allows to see what number of bad sectors are present on your hard drive.

Hard drive temperature:
High temperature can harm your hard drive. Stellar smart have temperature management features which are helpful to monitor and set the temperature alerts. This is required because sometimes dust enters the hard drive which in turn hinders the motor which affects smoothness of the motor. This increases hard drive temperature. It can sometime lead to hard drive failure.

There are some other attributes you can see on Stellar Smart like Spin up Time, Start/Stop Count, write error count etc.

3. Understand the sounds of hard drive.

Sometimes you can hear some strange sounds coming out of the hard drive, it might be alarming condition. There are lot of websites available which recorded sounds of various hard drives which are going to crash. You can check or match those noises according to your hard drive types. If you found the sound in there matching, hard drive replacement is due.

Take care of your hard drive, take care of your data!
