Hi, in this video, I will show you how to recover a lost partition using TestDisk.
Suppose I've just deleted a partition on Disk 1,
it now displays as Unallocated. 
First, let's go download TestDisk.
Google 'testdisk'.
OK, we found TestDisk - CGSecurity.
Click download.
And select the version according to your system.
Save the file.
TestDisk is a portable program. You don't need to install it. Just extract, and run it.
Once you have downloaded the file, extract and run it.
Open 'testdisk_win'
TestDisk operates in command line mode. 
On first step, it asks you to create log for storing technical information and messages. 
Press Enter to continue.
Next, you have to select media to scan for recovery.
I want to recover the partition on Disk 1 which is \\PhysicalDrive1. 
So select the media and press Enter
Select partition table type,
usually this will be detected by the program so press Enter to continue.
Select Analyse and press Enter.
Select Quick Search and press Enter.
TestDisk returns the result that it has found a partition as highlight in green color. 
Press Enter to continue.
If you haven't found the partition that you want to recover yet, you can select Deeper search. 
Please check documentation on TestDisk website for more information.
Otherwise, select Write to apply changes to the disk.
Press y to confirm write partition table.
Now it asks you to reboot the system. 
Click OK.
Select Quit.
Again, select Quit to quit program.
Now reboot your system.
Once you rebooted your system, open Disk Management.
Right click on Windows's icon and select Disk Management. 
You will now see that the partition on Disk1 is recovered and active, but no drive assigned to it yet.
So right click on the partition and select Change Drive Letter and Paths
Click Add.
And assign 'D' letter to the partition.
Click OK to continue.
Now I can explore my drive D.
OK. That's it. The end of this video.

Thank you for watching.
