 How to recover data from an unallocated area in a hard disk, HDD or SSD and external hard disk, USB drive or a memory card, SD, microSD, etc. Disk was deleted. And now there is some unallocated area. Instead of the disk, in Windows Disk Management window, this area is now marked as unallocated. In order to restore files from such unallocated area on the disk, USB drive or memory card, download, install and launch Hetman Partition Recovery. In the Disk Management tool, I can see that the unallocated area that I need is located on a disk with the capacity of 698 GB. I will recover the lost files from this particular disk. By default, the analysis type is full. I will have to wait until the scanning process is complete. As you can see, all lost files and folders are there.
