Even you do not know little or nothing about data recovery techniques. TestDisk is an easy-to-use data recovery program for both novices and experts.
#TESTDISK HELP SOFTWARE#
Once the scan is complete and you see all the files, then you can copy the files to the backup media.įinally, it is worth noting that TestDisk only handles software failures in drive data and will not help you in the event of a physical drive failure. An in-depth scan will take some time because TestDisk will read the entire partition block by block. TestDisk also automatically looks for file entries, although damaged or deleted partitions require a more in-depth scan. Once you see the drive, TestDisk will try to automatically detect partitions, including deleted partitions. If you are not sure where the drive you want to recover is located, use the command lsblk to get more information.
If the drive is not found, you need to specify the block device as a parameter of TestDisk, for example: sudo testdisk/dev/sda. (You may do it.) After that, the program will automatically look for any installed drives to use the log file. In addition, you need to run it with administrator privileges: sudo testdisk.ĭuring the first run, TestDisk will ask you if you want to start a new log file.
#TESTDISK HELP INSTALL#
In the Ubuntu operating environment, you can use the command sudo apt-get install testdisk to install TestDisk.
#TESTDISK HELP PC#
You can use TestDisk as a rescue tool for Windows or Linux partitions, but you need an Ubuntu online USB drive for You can boot into a separate environment on your PC and retrieve the lost files. (Of course, you can also delete the data itself, but usually this requires special deletion with a tool like shred.)
In fact, the delete operation only deletes the pointer to the data, allowing the operating system to write on these blocks.
TestDisk’s website claims that the program is designed to “help recover lost partitions and/or make non-bootable disks bootable provided that these symptoms are caused by faulty software: for example, certain types of viruses or human errors ( For example, accidentally deleting the partition table), etc." One thing to understand about storage drives is that when you delete a file or partition table, the data still exists on the disk. (This tool is also provided in the Arch Linux Extra file repository.) View Image It turns out that it appeared in the official Ubuntu file repository that was deployed with Ubuntu 16.04. The working principle of this tool is very attractive, but it does not provide a beautiful GUI interface to help. In fact, TestDisk has been around for a while, and it was even introduced on the PCWorld website in 2011. In the end, I found a program that can really help me - TestDisk. I didn't realize what I did until I tried to restart the machine and switch back to Windows 7.Īt that time, I felt a slight panic and comforted my mother that I promised to solve the problem. Before this, I did not resize the Windows partition on her hard drive at all. I didn't perform a detailed analysis beforehand (it was a bit difficult to tell), and it failed to back up my mother's data.
#TESTDISK HELP WINDOWS 7#
At that time, I tried to install dual system Ubuntu 16.04 and Windows 7 on my mother's laptop. I have personally experienced the above experience, because this is what happened during my most recent family reunion in upstate New York. When things happen to your own data, this is naturally terrible but when the problem occurs on someone else's machine, this feeling is unbearable. When you install an operating system on the PC of a friend or family member and suddenly encounter data loss, this may make you extremely frightened moreover, this is also a big event.
