How exactly does data recovery software work

It doesn't erase all of the file's data from the disk record, it just marks the disk location where the file is located as deleted. In this way, when you need to use this disk space to record other data, you can write it directly to these locations without retaining the original data.

The data recovery software can directly read the data on the hard drive, find the file directory, and then recover the data.

It is to recover data by scanning the hard disk track, and restore the information on the track to obtain the deleted file.

Data recovery software: a tool for data recovery and data recovery under software and hardware failures.

Finding out the cached data deleted by mistake on the hard drive is the principle of data recovery.

Deletion is a term used in computers that refers to the removal of unwanted files from the system's directory list to free up disk space for other operations. Deletion can be divided into two categories: tombstone and physical deletion.

Tombstone means that the data of the file is not deleted and emptied, but **e5 is added to the Chinese header of the fat table, followed by the registration of the cluster occupied by the file in the fat table, indicating the free space. Generally, the deletion we usually operate (such as emptying the ** site, shift+delete key combination to delete files) is tombtoning. In tombstoning, deleted files can be recovered as long as no new data is written to the disk space, causing the data to be overwritten.

Summary. Data recovery software refers to the data recovery and data recovery processing tool under the user's software and hardware failures due to sudden computer crash and power failure, accidental deletion of important files, computer poisoning, unreadable files, sudden system crash, misoperation, misformatting, computer virus attacks, etc.

The basic unit of data stored in a hard disk is a sector, which we can understand as a page of a book. When we install or buy a portable hard drive, the first step is to facilitate the management of partitions. No matter what kind of partition tool is used, the first sector of the hard disk will be marked with the number of partitions of the hard disk, the size of each partition, the starting position and other information, the term is called Master Boot Record (MBR), and some people call it the partition information table.

When the master boot record is corrupted due to various reasons (hard disk bad sectors, viruses, misoperations, etc.), some or all of the partition will naturally be lost, according to the data information characteristics, we can recalculate the size and location of the partition, manually marked to the partition information table, the "lost" partition back.

Who has used data recovery software??? Is it really possible to recover data?

Some data can be recovered, depending on what data you want to recover.

Below is a simple data recovery step by step diagram:

After opening the software, select the recovery scenario you need, here take Misformatting as an example, click Misformatting.

2.This comes in to the formatting partition selection.

3.Wait for the software scan to complete, and the data will form a list, and you can restore it to your computer desktop or hard disk as needed.
