Hard disk drives are a very popular and important form on data storage medium for the computers. They are compact and can support large volumes of information. But with the complexity of its design, it is usually pretty difficult for a layman to predict what exactly a hard drive problem is when it occurs. They end up doing more damage to it than good because of their dabbling in things quite out of their area of expertise.
One such hard drive problem occurs when one starts hearing scarping sounds even though the hard disk seems to be powering up just fine. If such a situation occurs, it is highly recommended that you immediately stop using that hard drive to avoid any further damage. These types of sounds are caused by loose read/write heads, which affects the disk platter and causes damage to the magnetic storage medium. It is possible to solve this hard drive problem if you try and replace the broken read/write arm with a working one. Special care must be taken when trying to clean off the broken fragments on the disk platter as you may cause scratches, which may lead to further data loss. It is recommended that you save your hard drive in a cool and dry place and seek technical assistance to improve your chances of data recovery and avoid hard drive problems in the future.
Data recovery from damaged hard drives might seem a very daunting and ominous task to anyone who has not had some previous encounters which these sorts of hard drive issues. But most of the times the problem is not as complicated as it may seem and you can save yourself quite some time and hassle if you can properly diagnose the problem and perform the steps necessary to save your data. One such hard drive problem is that although the hard disk powers up, it does not mount and no distinct sound of the read/write arm is audible. This usually occurs because of the overheating of the hard drive, which causes the metal components to expand and stick to one another. This will cause deletion of files and folders and you may be prompted to format your hard drive.
In order to remedy this hard drive problem, first detach the hard disk drive from your computer and allow it cool to room temperature. Then by using a vacuum pump remove all air from an antistatic container and place the hard disk in it. It is very important that the container be antistatic as sparks may cause further data loss and damage to the ICs. After placing the disk in the container, place the container in a refrigeration unit and allow it to cool for 30 minutes. After taking it out of the refrigerator, allow it to settle for 5-10 minutes before attempting data recovery. You should have an alternate data storage unit on hand to store the recovered data.
