Copy HPA data of Hard Disks, let UReach Duplicator help you!

What is HPA? HPA is Hidden Protected Area or Host Protected Area, which is usually located at the end of the hard disk.


HPA is the data space that the user and the operating system cannot access. Only special ATA commands can set up, and it is usually used by the manufacturers of hard disk.


HPA is often used to store preloaded systems, recovery data, system diagnostics and backup tools, which will change the maximum available capacity of hard disks. For example, the original maximum available capacity of the hard disk is 1000GB, after the HPA of hard disk is set to 100GB, the system will consider the hard disk capacity to be only 900GB.


The manufacturers of hard disk can do the following functions by setting the HPA of hard disks capacity:


  1. Controlling the quality of hard disks:

A 500GB hard drive needs to pass the 480GB quality inspection, so the bad quality areas are blocked and shipped with 480GB capacity.


  1. Multiple booting:

The system provider can place multiple booting systems in HPA area, and start them according to different purposes. The HPA cannot be accessed, so the operating system can be protected.


  1. Storage of special systems:

Different industries will store some special systems in HPA for different applications according to their needs.


  1. Protect confidential data:

Storing confidential data in HPA, so that others cannot access the contents of HPA arbitrarily.


When copying the data of hard disks, there is a low probability that some booting systems will be stored in the HPA. If the HPA is not copied, it will cause the system to fail to boot.
