Whether the problem is due to a logical failure or a mechanical one, there is a good chance that the data can be recovered successfully.
In case of a logical failure, the lost data may still reside on the disk, but simply can't be accessed. 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 rec
overable.
In a mechanical failure, 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.
