What is data rescue? Tips to avoid losing important data in your computer


Data recovery (data recovery) is the use of software / methods to recall or recover lost data from storage media. Data retrieval works well in situations where data is accidentally deleted, formatting an affected hard drive, reinstalling Windows, losing partitions, and system boot errors, etc.


Data recovery also refers to situations where specific information is not accessible due to the logical or physical damage of the device.

1. What is data rescue?

The recovery of lost data can be done right on the storage media including hard drive, solid state drive, USB, laptop or desktop hard drive, flash drive, memory card or SD card, etc. Data Recovery will search for desired files around the storage area of ​​the device and restore them successfully even when the drive has stopped working or cannot be accessed normally.

2. What is data loss?

Deleting files from a stored location does not mean that they are permanently lost, so such cases are not called data loss. Users can find them in the system’s trash folder and easily recover. Data loss situations include not being able to access the device’s files or files that are no longer on the device where the problem occurred.

3. The causes of data loss

3.1. Logic error

This type of error occurs with most hard drives, both traditional and modern. In the case of a logical error, the user will not be able to access the drive but can still see it on the BIOS or in the Disk Management section. Corrupted file system, operating system error is a leading factor causing logical errors and preventing users from accessing normal stored content.

The data is what is important for the computer

Data rescue is the best option when you unfortunately encounter logical or physical errors on the storage drive.

Because the internal structure of the drive is intact, undamaged, it is possible to successfully save all data if carefully monitored. You can search for data recovery alternatives like a recovery program or ask for the help of dedicated data recovery experts.

3.2. Physical error

For devices with physical errors, users will not be able to access the device, and the only way is to take the computer to data recovery experts.

4. How does data rescue work?

The data is stored on hard drives (made of metal oxide) that spin at speeds of 800 to 15,000 rpm while reading or writing data at very close distances of the disk surface. Damaging the hard drive will result in permanent damage to the stored data and cannot be restored. With the need to increase storage capacity, manufacturers often try to compress more data on the surface of a smaller hard drive, making the data rescue process more complicated and time-consuming.

In fact, when deleted from the storage device, the data is still not permanently lost. Instead, it continues to exist around the visible storage device and can be recovered by tools. data recovery or data retrieval service. Data recovery uses powerful algorithms to deeply scan storage devices (storage areas of the device) and list all items marked as deleted.

In other words, the data recovery tool collects portions of deleted or formatted files from the storage device’s MBR (main boot record) and allows users to preview the files before rehibilitate.

However, in case the file you are trying to recover is seriously damaged or infected with a virus / trojan, modified the header content of the file, advanced data recovery software will not be found either. them.

5. Tips to avoid losing important data

With the latest technologies, users can effectively handle data loss. Cloud storage, backup drives, built-in operating system utilities to store files, etc. are common ways you can avoid data loss.

Businesses can also opt for cloud storage to protect huge amounts of data, allowing access on many different servers, from anywhere in the world.

In addition, create a backup and distribute it on different storage channels like backup drive, recording copy data to CD or DVD can reduce the risk of data loss even when the main source is inaccessible or permanently damaged.
