About Head Crash

This would not be wrong to address hard drive as the soul of data storage in computer systems. Hard drive memorizes each and every bit of data that you enter in the form of files and losing data is one of the worst computer experience faced by a user. We may start believing that computer hard drives can store data permanently as of the efficient and spacious appearance they give. But, the fact runs ironically as these are the major factors, causing hard drive failure. Congested data storage and high speed, though they make hard drive good at performance, but data stability gets distracted somewhere and so hard drive recovery procedures come into play.

Hard drives’ internals are extremely sensitive to even the minor faults. Hard drive stores data on the stacks of rotating metallic platters. For each platter surface (Except the extreme lower and upper one), there is a floating magnetic head which is responsible for moving data back and forth.

In normal working conditions, head never comes in contact with the platters and reads/writes data in the form of impulses. But worse condition arises when this arrangement suffers faults. If due to any cause, like jerks, head comes in contact with the platters, there are high chances that data may get damaged beyond the scope of hard disk recovery. Here, I am referring to the area which comes in contact with the malfunctioned head as magnetic film may get scratched off, however, other areas still retain data intact, though inaccessible.
