When should you use DiskGenius to perform partition recovery? Below are typical cases:

  • A partition gets formatted by mistake, and you want to recover lost files stored on original partition.
  • A partition was damaged and unreadable, and Windows prompts that you need to format the partition before you can use it. The corrupted partition contains important data.
  • A partition is lost and cannot be found in Windows Explorer and Disk Management, and you want to recover it.
  • Due to improper operations, such as repartition the wrong hard drive while installing Windows OS, removing all existing partitions.
  • Partition table gets corrupted due to hard drive damage, virus attack, etc., all partitions are disappeared.

As to the first two situations, the partition is formatted or corrupted instead of getting lost, thus, what you need to do is scanning the partition to find lost files. Refer to this guide on how to recover lost files: A Detailed Guide to Recover Lost Data with DiskGenius

Once a partition gets deleted, the disk space becomes unallocated. You can scan unallocated space to restore deleted or lost partitions back to their original status. This guide will show you how to look for lost partitions on unallocated hard drive using DiskGenius. When all lost partitions are found by the software correctly, you can choose to save them to partition table. After that, these restored partitions will be assigned drive letters by Windows and then mounted to File Explorer.

Note: Do not create new partitions on the hard drive or repartition the hard drive before lost partitions are recovered correctly.

Step 1. Install and launch DiskGenius. Select the unallocated disk space and click "Partition Recovery" button. Then click "Start" button and the software starts to search for lost partitions.

Step 2. Click "Reserve" or "Ignore" button.

Usually, the scanning process will find out more partitions than you want to recover, and you need to choose "Reserve" or "Ignore" for each found partition. Preview files in the partition before making the decision. Click "Reserve" only when the partition is the one you want to recover, otherwise, click "Ignore".
