Data recovery from crashed hard disk drive

Technological advancement has added to the utility of computer and today it occupies most important position in every field. It in itself is a great invention then also problems keep taking place, one which is ought to be the worst is hard drive crash. In spite of the huge data holding capacity and reliable features of hard disk, problem of mechanical failure is not yet resolved.

Head crash accounts for maximum number of hard drive failure cases. It occurs when disk’s read/write head touches rotating magnetic platters and meanwhile scratches it and cause damage to platter’s magnetic surface.

When such a problem takes place, disk stored data is lost meaning to say it cannot be accessed. The situation is quite different from accidental file deletion, in which the files are restorable by dragging from trash bin or use Mac undelete software and get back your files.

This and such other damages occur suddenly without the user being able to detect and prevent the problem. However, some of the common signs indicating crashed hard drive include-

>>   BSOD (Blue screen of death) – taking place due to damaged or incompatible applications, registry errors etc
>>   Hard drive making clicking/grinding noise- read/write head spinning close to magnetic platters
>>   System rebooting itself
>>   System freezing, displaying errors at boot up and while working etc

Read write head is positioned on disk platter correctly which causes difficulty in data inaccessibility, in the situations mentioned below-

• Hard drive wear and tear
• Dirt particles interfering in the usual processing of read/write head
• Damaged armature arm which holds it and avoid getting in touch with platter
• Improper power causing trouble in movement of drive’s head and ultimately leads to crash

In the above case, system use should be stopped in shortest possible time and help of data recovery expert service should be taken. After that for crashed hard drive data recovery professional tool is required that is equipped in reading the drive with its powerful algorithm and extracting data in accessible form. Data recovery crashed hard disk restores original form of data stored onto a different drive and never on the same drive from where recovery is being carried out as this affects usual process by overwriting preexisting hard drive data.
