Has the hard drive failed in your computer? Maybe it no longer starts. Do you just get a blue screen or hear a clicking noise? That is a sign your hard drive may have failed.
How Hard drive data recovery works?
Eventually, all hard drives will fail. The only question is, when?
Many drives work flawlessly for years, while others may fail when you least expect it.
When the unfortunate does happen, we can restore data from the failed media and provide replacement media.
Hard disk drive problems generally fall into two categories:
Logical Failure
In case of a logical failure, the lost drive data may still reside on the disk, but simply can't be accessed. Logical failures include accidental deletion or formatting of the data on the drive, corruption, lost partitions, or software errors.
For example, when a file is deleted, the data is not actually erased from the hard drive; rather, the spot where the file was stored is allocated for reuse. Until that spot is actually used for storing new information, the data that was deleted is still recoverable.
Mechanical Failure
In a mechanical failure, there is a physical problem with the hard drive - one of the many internal mechanisms of the drive are broken. The drive may not spin correctly, or may not spin up at all, and may make clicking noises or exhibit other abnormal behavior when operating.
Some common mechanical problems include head crashes and faulty motors.
It is possible that all of the data is present and intact on the hard drive, but because the actual mechanism inside the drive is physically damaged, the data simply can't be accessed.
Physical hard drive repair is a very delicate operation, much like a surgery, and if proper precautions are not taken, the operation could become a disaster. That's the reason why it's so crucially important to find a data recovery specialist you can trust.
Some problems, such as bad sectors and faulty firmware, fall into both categories.
