Hardware Related Data Loss
When the storage media itself has incurred physical damage, the result is usually devastating, and most often, recovery is costly.
Hard Disks
How Hard Disks Work
Wear And Tear
The lifespan of hard disk averages 3 to 5 years. This is not surprising considering the working process of a hard disk.
If you lose files due to a physical fault, chances are that a read-write head failure has occurred. Since the distance between the head and platter is very small, any particle which disrupts the read procedure causes the head to “crash”, so to speak, onto the platter. This causes the head to scratch the platter, resulting in even more particles.
Once the platter is scratched, you lose data permanently.
However, prolonged use is not the only reason a head crash occurs. Physical trauma, such as when a laptop is dropped, can also cause head crash.
For this data loss situation, please take the proper data loss procedure:-
Drive Motor
The drive motor of a hard disk enables all the physical mechanism to work. It spins the platter and moves the head to read the platters.
Once the motor is dead, the mechanism of the hard disk won’t work. The hard disk seems dead even though the platter remains working condition.
