Data recovery is an essential process in computing that involves retrieving lost, damaged, corrupted or inaccessible data from secondary storage devices when the data cannot be assessed in the normal way.
Data recovery comes into play due to several factors. The most common scenarios where data recovery is needed are an operating system failure, logical failure of the storage devices, physical damages to the device, accidental deletion and formatting, and malfunction of the storage device. The simple solution is to copy the data from the damaged device to another device that works fine.
Why do we need Firmware Repair tools then?
Often a data storage device might be self-damaged. This can be understood when there is no detection of the drive or the drive shows 0 space available in BIOS, Smart errors, and so on. In such cases, the methods mentioned above are not applicable as the hard disk is not working.
Now every hard disk has its own management script, also known as the firmware. The firmware consists of different command levels like G-list, P-list, T-list, SMART table and others. Using these firmware repair tools, the damaged firmware modules can be repaired and passwords can be removed before working on the data recovery process. The firmware tools can repair firmware failures of hard drives and helps us to recover the data from such hard drives.
Functions that the firmware repair tool can perform:
Repair two hard drives simultaneously.
Adding common commands quickly and manually for direct execution.
Read/ write firmware modules
Full HDD tests
Read or write SA areas
Common failure solutions and secure data recovery.
Translator operations and Smart operations.
The common issues that are easily repaired by using firmware repair tools:
Detection in BIOS, yet not showing in disk management.
Slow performance of the hard disk
Dump error in windows
F1 error at start-up
SMART error detection

6.Introduction to Samsung, Toshiba and Hitachi firmware and repairing.
In the data recovery market, there are limited persons who want to share their data recovery knowledge because they were spending a lot of time and money in research and practice to find out and test those data recovery knowledge and tips.
This Advance firmware Data Recovery Training course is the most hands-on and highly technical logical data recovery course. The goal of the advanced firmware Recovery Training course is to share knowledge and tips on firmware tools, workflow and provide a better understanding of firmware problems and solutions to all our users and help them in an easier way of success in the data recovery field.
