Like a heart to human, Hard Drive is an essential part of a whole computer. It is designed to store a great deal of data and programs for PC users so that those data can be used at a later time.Running a software program, sending and receiving e-mail and saving Word documents all require the data from the hard drive. As computer systems become more and more advanced, the roles that the hard drive plays have increased. However, once the hard drive gets some problems then it would absolutely be a big trouble or disaster to any PC users. Therefore, we had better maintain the hard drive in our daily use of computer regularly in order to avoid any possibility of HD crashing.

Hard Drive failure is predicable actually so you do not have to worry about that your HD would crash suddenly when you wake up some day. Generally speaking, if the HD is going to get malfunction, there should be some symptoms appearing to warn you before it getting crash.

1.Pops-up S.M.A.R.T Message. S.M.A.R.T is a monitoring system for computer hard disks to detect and report on various indicators of reliability, in the hope of anticipating failures.The purpose of S.M.A.R.T. is to warn a user or system administrator of impending drive failure while there is still time to take preventive action, such as copying the data to a replacement device.If you find a alarm from S.M.A.R.T, you had better pay attention to the potential physical failure otherwise it would not run properly if you just let it be. To use some hard drive diagnose tools to fix malfunction in time is really necessary.

2. If your computer fails to recognize the hard drive in BIOS (Basic Input Output System) from time to time or computer is able to recognize hard drive but the operating system can not find the HD, that is a another portent of the HD malfunction. I suggest you export and store the data to another place and then take your hard drive to PC shop to have a inspection as soon as possible.

3. Sometimes you will find that you can enter Windows system smoothly but you would keep receiving error message when you try to run any applications. And at the same time, hard disk scanning function does not work properly. Computer is deadly slow even gets freeze during the scanning. Such symptom could probably be caused by the hard drive malfunction or by the registry of system. It is highly recommended that you download some registry cleaning programs to detect errors on your computer at first to preclude the soft crash.

4. If you use hard drive scanning program to find out HD errors or even bad track directly, I advice you use HDTune to repair HD problems immediately.

5. Computer freezes withine the initialization of Windows system. In fact, it is quite hard to identify which specific part of computer causes this phenomenon. Low quality of memory, CPU fan stops working, or virus’ attacking etc. So you need to preclude those factors one by one.  

Tips: Here I strongly recommend you backup your important data or files so that you would not feel frustration if your hard drive gets problems one day.
