You have deleted a partition from your hard drive, for example, after wanting to import a hard drive to a new configuration and having done something wrong. For example: after having decided to transform the hard disk into basic disk in the management of the disks present in the management of the computer of Windows, whereas it was necessary to choose "import a foreign hard disk".
It is possible to recover the data, although now it says "unallocated space". Above all, do not format the hard disk or create new partitions. Otherwise, it will be much more difficult to find your lost information. At the moment, only certain sectors of the disk have been deleted, but most of the data can still be recovered.
For this we use the DMDE software which is the most advanced software. Of Russian design, this software is very intuitive, the free version is sufficient for use by an individual.
Select the partition that bore the name of the original partition. There should be an "F" in the flags column. Right-click and create an image that will be saved on another larger hard drive. It is indeed necessary to make an image of the hard disk that one wishes to analyze to prevent the data from being lost (transformed into magnetic dust) during the scan.
Then we will open this image with the DMDE software. We will select the partition, right click and launch a full scan of the selected partition. It may take several hours, especially if your partition is larger than 500-750 GB.
Once the scan is complete, we will double click on the partition at the top. The software will then build a virtual file system for you to recover your data. You will have to recover each file by checking the corresponding box, then right-clicking and finally choosing "recovery".
If you have a complex tree of files and folders, you will need the paid version, the cost of which is not excessive. The free version does not allow selecting files through directories, only selecting them directly, which takes more time.
You will therefore need a spare hard disk larger than your damaged disk, to house the recovered image and data:
