AOMEI Post By AOMEI Updated June 19, 2024


Once, one of my friends had suffered a lot from data loss. He used to save all his private matter on partition D, including photos, videos, music and things like that. One day, when he started his PC, he couldn't find his partition D. He was so disappointed that he began to recall what could be the cause for this. He sought in his mind what he had done the day before with his computer. After some brainstorm, something caught his attention. It seemed that he accidently deleted his D partition...It was too late to mourn so he thought about me and told me that. With my suggestion, he successfully got his lost partition back with all his private data.

Why do you need a partition recovery tool?

To learn partition recovery, we should first give you an exact impression about partition. Generally, a disk is always divided into several parts, and each part is called a partition. It is very useful to divide hard disk into several partitions because each partition will work like a separate disk drive. You can use it to store different categories of data without confusion. If a hard disk only has one partition, once the partition gets lost or is deleted accidentally, all data will be lost.

In fact, there are several causes for partition loss. Some are common, while others are not. To restore a partition, it is usually necessary to understand why the loss occurred:

Accidental deletion: Unfortunately, even pros make this error since the human aspect is present in virtually all situations.

Bad sectors: They might make it difficult for the operating system to recognize a partition.

Damaged partitions: A lost partition might result from damage to the partition table caused by a virus, other malware, or an improper disc operation.

Power problems: Power outages generate power surges, which can destroy the whole hard disc and all of its partitions.

However, the thing is if there is more than one partition on the disk and one of them gets lost or is deleted, what you lost is only the data on the lost partition and data of other partitions on the disk are still there. Fortunately, if you have lost one or two partitions, you can still have them back with the partition recovery tool.

Partition Recovery is actually a tool of recovering your lost partitions that were accidentally deleted or damaged due to hardware/software failure, virus attack, or some other unknown reasons, as long as they were not formatted/overwritten after deletion. Here we will show you how to recover partitions with the Partition Recovery Wizard built-in AOMEI Partition Assistant, which may restore partitions that were deleted a long time ago.

How to recover deleted or lost partition

Prerequisites for partition recovery

Choose Disk

3. You will get two search modes in the pop-up window:
Fast Search: scan the first sector of each partition on the selected disk in order to find out the deleted or lost partition quickly. (Recommended)
Full Search: scan more in-depth search every sector of each partition on the selected disk. Consequently, it needs more time. You could choose this method when the Fast Search fails.

4. Once the deleted/lost partitions are found, they will be displayed in the list box, and highlight the partition which you want to recover and click "Proceed" to continue.

Select Lost Partition


  • The partitions be found are listed in details. You can see their special information: file system, capacity and flag (primary or logical).
  • You can double click the partition to check the files to see whether the partition is the one you want to recover. To do this, you can also directly click "Explore files in this selected partition" button after choosing the target partition.
  • You can select more than one partition by ticking in the box which lies in front of each partition information and recover them all in one time.
  • The final status after restoring can be seen in graphic bar. The partition with blue cross is the partition you are going to recover.

5. After that, the AOMEI Partition Assistant will give you congratulations to notice you the lost/deleted partitions have been recovered successfully. After that, you can see these files in My Computer.




Followed by the above steps, the deleted partitions are recovered successfully. Once partitions are recovered, data on the drive will also be recovered. And you can check files/folders on the recovered drive.

This wizard is mainly used in the following situations:

If your system partitions are resized but it is unable to boot into Windows successfully, you can create a bootable media and boot your PC into WinPE to recover partition on your system drive. After it is recovered, you can reboot your PC.

If data on one of your data drives is lost or one partition is deleted by mistake, you can directly use the partition recovery tool to recover lost partitions and data on it. You can recover lost partitions as long as these partitions are not formatted or erased.


  • If you can't find those deleted or lost partitions by using Fast Search, try another way: Full Search.
  • This feature could only support recovering deleted partitions. If the partition has files, after the partition been recovered, the files will also come back automatically. If you want to recover files from formatted, corrupted partition, you need to use professional data recovery program.
  • The recovered partitions may have no drive letter. If so, you could not see the partitions in "My Computer". In this situation, please reboot computer and then launch AOMEI Partition Assistant to manually assign a drive letter to the partition by right clicking the partition -> Advanced -> select Change Drive Letter.


Q: What should we do if no partition can be displayed?

A: If you use the Fast Search, you may try Full Search to scan again. If no partition is displayed with Full Search, currently the tool is unable to recover partitions on the drive. You may try other professional data recovery program.

Q: Why is the search or recover process stuck?

A: There might be bad sectors on the drive. You might first do defragment and use chkdsk/ r to check and fix the drive and retry. Or, you can try to create a bootable media and then boot your PC into WinPE to do partition recovery.

Q: How to check which partitions to recover since there are multiple partitions listed.

A: You can double-click the listed partition to check  files on it to see whether the partition is the one you want to recover.

Q: Why the listed partitions cannot be ticked to recover.

A: The possible issue is that the drive is a MBR drive and the whole drive space is over 2TB. Due to the 2TB usable space limitation on the MBR drive, it is unable to recover a partition over 2TB on a MBR drive. In this case, you can first convert the MBR drive to GPT and retry recover.
