What is Physical Data Recovery / Media Level Data Recovery ?
Physical data recovery is the term used in data recovery industry for the drives which has damages internally like Motor or Read write heads. The work that has to be performed is in class 100 clean room lab and expert data recovery tools are required to complete the data recovery from the mechanical hard drive.
The hard drives internals consists of two types of components, one is the reading heads to read data, second is magnetic platter which rotates with help of motor and holds data. The Physical data recovery is required for the drives with read write head failure, motor failure and internal magnet failures. The distance between magnetic platter surface and read write heads will be very small in micrometers, the drive fails when the reading heads could not able to read the data anymore due to multiple issues.
The drives goes into physical damages due to many reasons as follows:
- Dropping the hard drive from small or large heights,
- Overheating issue, the drive drive motor and internals reach above sustainable temperature and drive physically fails to read and write,
- Spindle motor seizes to work or move due to fall or sudden power down,
- Manufacturing defects of certain model of drives,
- Read write heads broken down and could not read magnetic platter surface,
- Out of multiple read and write heads, the drive could not read data from few heads, considered as some heads bad or partial physical issues.
- Water or fire issues in the drive or computer leads to physical issues.
The Physical data recovery from the drive needs to be handled in professional way by our engineers

Bearing and Motor level failure:
Under normal operation, your hard drive’s platters are spinning at thousands of revolutions per minute. Modern hard drives tend to spin at 5,400 or 7,200 RPM. Enterprise-class hard drives spin at up to 15,000 RPM. The high rotational speed of your platters is what enables your hard drive to access information so quickly.
But like most hard drive components, the spindle motor is delicate and vulnerable. A spindle motor failure can happen for several reasons. Most commonly, it is the result of physical damages. Environmental conditions or human errors can also cause the hard drive spindle motor’s lubricated bearings to dry out. Without lubrication, the heat and resistance generated by friction becomes
