Mechanical Hard Drive Data Recovery

Mechanical recovery is necessary when the storage media device has experienced physical damage to its internal parts. In order to achieve a successful recovery, those damaged internal parts would need to be replaced inside of a clean room.

The most common cause of data loss is physical media damage, whereby the hard disk drive receives a physical shock causing the head to hit the platter or damage one of the moving parts. This condition will not always cause a failure straight away but the condition of the platter and internal parts will probably deteriorate and then the failure will occur. This will potentially cause the most damage if a laptop or mobile device is dropped at the same time the HDD is reading or writing data.

How this happened?

Mechanical failure – the most severe type, involves mechanical or electronic failure of the drive itself. Most mechanical problems are the result of damaged disk due to abuse, wear, and excessive write operations. Other damage occurs to the electronic controller card attached to the drive.

Hard drive or device physical damage can be a result of a manufacturer’s defect, a physical impact such as a device being dropped or bumped while it is running, or fire and water damage. The damaged chips or components manifest problems such as bad track, scratches on platters, motor seizure, head crash, burnt PCBA and other malfunctioning components.

Few most common cause of physical media damage:
  • Disk is recognized by system but cannot be read normally;
  • Disk cannot be detected via operating system;
  • Disk cannot respond to system commands;
  • Disk freeze due to bad sectors;
  • Hard drive makes a “clicking” sound like “tick tack”
