This article mainly introduces the relevant knowledge of how to use Linux's estdisk tools, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value, I believe you will have something to gain after reading this article on how to use Linux's estdisk tools. Let's take a look at it.

Estdisk is a powerful free cross-platform data recovery tool. According to a brief introduction on its website, this software is mainly designed to recover lost partitions and fix problems in which the system cannot boot due to human or virus-induced partition table errors.

Use TestDisk

The TestDisk website claims that the program is designed to "help recover lost partitions and / or make bootable disks that can no longer boot; provided that these symptoms are caused by faulty software, such as certain types of viruses or human errors (such as accidental deletion of partition tables), and so on." One thing to understand about storage drives is that when you delete a file or partition table, the data still exists on disk. In fact, the delete operation simply removes the pointer to the data, allowing the operating system to write on these blocks. (of course, you can also delete the data itself, but usually this needs to be specifically deleted using a tool like shred.)

You can use TestDisk as a rescue tool for Windows or Linux partitions, but you need a Ubuntu online USB drive so that you can boot to a separate environment on PC and retrieve missing files. In the Ubuntu runtime environment, you can use the command sudo apt-get install testdisk to install TestDisk. In addition, you need to run it with administrator privileges: sudo testdisk.

Easy to use TestDisk

On the first run, TestDisk will ask you if you want to start a new log file. You might do it.) After that, the program automatically looks for any installed drives to use the log file. If the drive is not found, you need to specify the block device as a parameter to TestDisk, for example: sudo testdisk / dev / sda. If you are not sure where the drive to restore is located, use the command lsblk to get more information.

Once you see the drive, TestDisk will attempt to automatically detect partitions, including deleted partitions. TestDisk also automatically looks for file entries, although corrupted or deleted partitions require more in-depth scanning. An in-depth scan will take some time because TestDisk will read the entire partition block by block. Once the scan is complete and you see all the files, you can copy the files to the backup media.

It is worth noting that TestDisk only handles software failures in drive data and does not help you in the event of a physical drive failure. As always, you should really keep a good backup of your data. The reason is simple: with complete and up-to-date backups, if something goes wrong with the drive, you are free to erase the data on the entire drive.
