To recover the data from a specific type of hard disk failure, specific methods are applied. Software programs are used for addressing the issue of logical failure in the hard drive. There are many software programs on the internet which are available for free or have minimum charges. The reliability of such software programs should be put under a microscope before their use. With the help of these programs, a person with basic computer knowledge can attempt hard disk data recovery for the hard drive with logical failure.
Firmware failure issues are more complex and need to be dealt with with a different approach. For firmware hard disk data recovery, we need hardware-based programs and tools. The total capacity of any hard drive is divided into the Service area and the User area. These are two important parts of any hard disk. The service area has control over the User area of the hard drive. The user area is an actual space on the drive which allows the user to store the data. The tools used for firmware failure cases allow access to the service area. The creation of bad sectors in the service area is responsible for most firmware related drive failures.
