TestDisk is a data recovery software is very good and it's free! Software is designed to help recover lost partitions or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting Partition Table). Partition table recovery using TestDisk is very easy to use.


TestDisk can:• Fix partition table, recover deleted partition• Recover FAT32 boot sector from its backup• Rebuild the boot sector FAT12/FAT16/FAT32• Fix FAT tables• Rebuild NTFS boot sector• Recover NTFS boot sector from its backup• Fix MFT using MFT mirror• Move Backup superblock ext2/ext3/ext4• Undelete files from FAT, NTFS and ext2 filesystem• Copy the deleted files and partitions FAT, NTFS and ext2/ext3/ext4.This is how I have practiced:

Select "Backup" to continue the process. After that we can do some commands on the list that appears partitions. "*" Indicates your primary bootable [usually local disk (C :)]. Here we will be a little to feel comfortable that the partition is read not only C. Press "p" to see the contents of an existing partition. How happy when I saw the files we lost partitions intact. press "q" to return. Press the right arrow left and select "L" or "P" to change partition status, primary if you choose "P" or logical if the "L". The "D" to delete the partition. But let's just leave it as default. To continue press enter.

If we want to find some more partitions then select "Deeper Search" but select "Write" to immediately restore (write) to the disk partition structure. After that there is a prompt to create a partition table press "Y" to menconfrim.

 

The restoration process is complete and now restart your operating system first. Once the process is complete reboot your lost partitions look reappears
