Data recovery software is a tool that helps users retrieve and recover lost data. Data recovery software provides logical level recovery and physical layer recovery functions. The former usually refers to data recovery in cases of accidental deletion, wrong cloning, wrong formatting, partition loss, virus infection, etc. The latter means recovering lost data caused by physical hardware damage, such as motor stuck, disk bad sectors, disk not recognized, head shift, etc.
There are many data loss situations where data recovery software can be helpful. It may be the only way to restore lost data in some severe cases. Here are some common examples:
Data recovery software helps restore lost or deleted files in each of these cases. However, there is no guarantee that it will be successful in every situation. For example, suppose the damage to the drive is too significant, and the data is lost permanently. In that case, the data recovery software may not be able to piece it back together successfully. Whatever the cause is, it is always worth trying data recovery software before giving up.
To understand how data recovery software works, you first need to know how computers store files.
When we save a file to the hard disk, the system will first write the file name and size in the file allocation table and continue to write the starting position of the file content in the data area according to the free space in the file allocation table. Then start to write the file's actual contents to the data area, and a file storage operation is complete.
Data recovery can be defined as a process of obtaining information located on a storage device that cannot be accessed by standard means. When we delete a file or perform a formatting operation, the system writes a delete mark in front of the file in the file allocation table. It clears the file allocation table, indicating that the file has been deleted and the space occupied by it has been released, and you can save other files now.
Therefore, when we delete the file and want to get it back, we only need to remove the deletion mark with the help of data recovery knowledge and tools. The data recovery software can scan your hard drive for these deleted files and then recovers them.
Of course, there are some limitations to data recovery software.
Many different data recovery software programs are available on the market, both free and paid. So, which one is the best? The answer to this question depends on a few factors, such as the type of data you need to recover, the size of your hard drive, the operating system you are using, the difficulty of data recovery, and your budget.
