How to Perform Data Recovery from Physical Media

In computer engineering data recovery is an approach to recover lost, corrupt, inaccessible damaged, formatted, or secondary storage from removable media, computers or other devices, if the data still can’t be accessible in a normal manner. Data recovery could be a procedure where one has to physically access and analyze the data. Data retrieval may also be accomplished through manipulation of the data or its storage medium. Data recovery is an essential process in the information technology infrastructure (ITI). It is a crucial element in IT recovery planning execution, restoration, and business continuity. There are three major types of data recovery including file recovery, data recovery and operating system recovery.

What exactly is lost data? What is data? Data can be valuable data stored on either electronic or physical media. For instance, if an individual keeps all his important data on the form of a USB flash drive, he needs to keep the data on different storage devices so that when the time comes to retrieve any of the stored data and needs to access it, he’ll be able to access it easily. A typical user of a computer will not be able to determine which device holds the data or even how to restore it. Thus, in order to address this issue data recovery software is designed to retrieve any kind of data, even when the storage devices have been misplaced.

How to recover data? There are many ways in which you can recover data, based on its physical condition, purpose and the location. Physical and retrieval of data using logic are two of the most well-known methods of retrieving data.

Physical data recovery involves backing important files and moving important information to a flash drive or CD-ROM. The issue with this method is that if the computer crashes, you can never retrieve those saved files from the CD-ROM or flash drive. This is because if a human error occurs and the drive was overwritten with other data, then you won’t be able to retrieve it once more.


Logical data recovery is the method of backing up the parts of the system that are logical prior to a computer crash or hard drive overwrite. However, this method is not always successful if a virus attacked the system after the process was completed. For this type of data recovery, you need to download a third-party recovery software. This software scans the affected area to locate damaged files and locations.

Once the scanning is completed the data recovery software creates a list of the locations and files which were unavailable due to various reasons. Based on the information from the recovered files and locations the program then tries to locate the files and locations. In most cases this method isn’t effective due to human error. If one of the files is replaced by another file the recovery process is unsuccessful.

Backups are the third option that is rapidly gaining popularity for data recovery from physical media. ตรวจสอบธุรกิจ You can create multiple copies of files and documents and store them in different locations. If a computer system suffers an incident, it needs to access all backups that have been saved. Tape drives and external hard drives can be used for physical backups. Backups can be saved to your local storage. They will still be accessible even if the local storage drive is damaged.

While conducting the recovery process, it is essential that you back up all the important information. If you suffer a major physical loss, this might not be possible. Sometimes, data loss unexpectedly occurs when you are recovering. Before you begin the recovery process, it is important to create a backup.
