What is a Lost Partition in EaseUS Data Recovery Wizard?

Partitions may be lost due to power outages, accidental deletion, disk failures, or other issues. EaseUS Data Recovery Wizard is a dedicated tool designed to recover files — including photos, videos, audio, and more — from lost partitions on internal or external hard drives, USB flash drives, SD/memory cards, and other storage devices.
 
You can use the Lost Partition Rescue or Hardware Disk option in the software to recover your lost partition or files in the following two scenarios:

Scenario 1

If an entire partition has been deleted or lost, it will appear as Unallocated in Disk Management. You can refer to HERE to access Disk Management.


If you want to restore a lost or deleted partition, simply select the "Lost Partition Rescue" option from the list, and then click "Search for Lost Partitions".

Once the scan is complete, the software will list all recoverable partitions. Simply select the one you wish to restore.


Before restoring the partition, you can also double-click the found partition to preview its contents



Scenario 2

In cases where the file system is badly damaged, partition restoration may fail. Direct data recovery is often the most effective approach.


The process to recover files from a lost partition is similar to a regular data recovery. We recommend following the video guide available HERE to recover your files.
