Ontrack Data Recovery engineers classify hard drive data loss in two categories:

Mechanical failure - the hard drive is not functioning. The most common causes are head crashes and motor failures.
What Causes Hard Drive Failure?The list of incidents causing hard drives to fail and lose data is not limited, but some of the main causes that Ontrack Data Recovery services recover from everyday include power surges, overwriting, physical damages, natural disasters, and viruses.
How Ontrack Data Recovery Services Helps to Recover From Hard Drive Data Loss
Data recovery involves more than just replacing parts. Ontrack Data Recovery services use cutting-edge hard drive recovery tools and processes that come from heavy investment in R&D and 20 years experience. A sample of the expert techniques used include:
In case of mechanical failure, hard disk recoveries are performed in dust-free cleanroom environments where they are carefully dismounted, examined and processed.
Hard drives are imaged. A copy of the disk is made and transferred to a new system.
Ontrack Data Recovery tools can “force” the drive to read around the bad area.
NOTICE: Trying this on your own or through an inexperienced provider may lead to further damage to the drive.
