 to recovering data after deleting or creating new partitions on a hard disk, a memory card or a USB flash drive. User data can be lost as a result of deleting or creating partitions or as a result of changing the file system on a hard disk, a memory card or a flash drive. After a file system error or an incomplete operation to create, delete, or format a partition, a medium becomes unavailable in the Explorer. When trying to access the disk, Windows shows the message that the file system cannot be determined and suggests that you format the device, but don't hurry to format your device. The first thing you should do is to try recovering its data. Start the program at one partition recovery. In the physical disks list, find the disk you need to recover. In the analysis type window, select full analysis and check the necessary options. Now select the files and folders which you need to recover.
