Accidentally deleted partition and I can't restore it, this happened to my 500 gb nvme SSD in my laptop. Does any one know exactly what I have to do?I can't imagine the data being gone since I never overwrote anything so the data should still be there. Thanks for the help.

- Question from TestDisk & PhotoRec forum

SSD partition recovery issue bothers users much. The reasons or triggers of SSD partition loss vary among users. Just as the user in the example above, accidental deletion or misoperation may lead to a partition loss.

They may get busy as a bee attempting to recover the lost partition, and some users may doubt that if the SSD lost partition recovery is possible. Luckily, the answer is yes.

When discovering that the partition on the SSD is gone, do not panic or consider establishing a new partition. First and foremost, please cease using the SSD.

At this time, the space is identified as unallocated space by the Disk Manager when the partition is removed or deleted and will not be shown in the Explorer. If a new partition is created, the original partition will be overwritten, and the data in it will also be lost.

In a word, SSD lost partition recovery is achievable as long as the space is not overwritten by fresh data. Now, before coming to the solution part, it is necessary to lay a basic impression on users about the SSD and SSD partition loss.

Overview of SSD

In this part, you could get to know the definition of SSD, and the advantages and shortcomings compared with HDD.

What is an SSD?

SSD is what we usually refer to as Solid State Drives. It's a hard disk composed of integrated circuit assemblies.

Its storage media is classified into two types: flash memory and DRAM (Dynamic Random Access Memory). Intel's 3D XPoint particle technology is the most NVM (recent non-volatile memory) technology.

SSD VS. HDD

In addition to SSD, another storage device is the HDD, whose full name is Hard Disk Drive, it is a non-volatile memory that can retain stored data even when the power is turned off.

Compared with HDD, SSDs have faster reading and writing speed, no noise, anti-vibration, low average power consumption, and low heat. It also has some drawbacks: expensive, limited write times, read interference, difficulty to recover after data damage, and performance reductions.

However, Speed and capacity have always been the most challenging parameters of storage devices, and such devices must be small and power-efficient.

Because SSD offers a higher data transfer rate, greater storage density, higher reliability, and reduced latency and access time, most users choose SSD and utilize SSD as the system drive to enhance computer booting speed and performance.

No matter you are using HDD or SSD, users may encounter data loss issues. They may need to recover HDD partition or restore SSD partition.

Now, let us move on to the common reasons for SSD partition loss.

Causes of SSD partition loss

Partition loss on SSD occurs under various conditions. Some of them are listed as follows.

Inadvertent deletion. To err is human. No one can avoid mistakes all the time. Users may plan to delete a partition but delete the wrong one.

Partition table error. Improper operation or viruses in Master Boot Record can result in partition and data loss. Under such circumstances, users need to recover MBR partition table.

Power outage. When performing operations such as partitioning the hard disk, a sudden power failure may make the partition table unrecognizable, resulting in partition loss.

◆ Bad sectors. Bad sectors on the disk may prevent the operating system from recognizing the partition.

In the next part, we are going to talk about how to recover SSD partition.

How to perform SSD partition recovery?

Generally, when deleting a partition, the system removes the location info allocated by the hard drive. But, as long as the space is not overwritten, it is recoverable.

However, if you continue to use the computer after the partition is lost, recovery will be more difficult; the more you use the space, the more likely the space will be covered, and the less likely the data will be restored.

In addition to deletion, the volume may also disappear due to the missing of the drive letter and other reasons, and cannot be viewed and operated in Disk Management.

For a partition that has disappeared because there is no drive letter, the recovery method is very obvious: assign it a new letter, but the operation can be a little difficult - because users need to use the command prompt.

In the following, we will first provide you with the method of using the command prompt to perform SSD lost partition recovery.

Method 1. Perform SSD partition recovery using Command Prompt

Using CMD is quite dangerous, because users who are not familiar with CMD may type the wrong command, or misuse some commands, such as the "clean" command.

Attention: Make sure you have selected the correct disk and partition! You’d better check if it is right in every step.

Step 1. To open “Command Prompt”, tab on “Win+R” and in the dialog box type “cmd”, and then input “diskpart”.

Step 2. Input “list disk” to view all the disks on your PC. Then input “select disk m”. Here “m” refers to the number of the disk that contains the lost SSD partition on the hard drive.

Step 3. Input “list volume” to view all the partitions in this disk. Then input “select volume n”. Here “n” refers to the number of the lost SSD partition.

Step 4. Input “assign letter x” to name the partition. Remember to use a new letter different from all the existing letters.

Method 2. Perform SSD partition recovery with AOMEI Partition Assistant

Compared with the method given above, turning to professional partition recovery tool could be much safer and easier. Because there is a great potential that users might input the wrong command line or select the wrong disk or partition, which may cause an unimaginable dangerous result.

So if you discover that the partition has been lost or deleted, you might as well use a professional SSD lost partition recovery program to recover the partition and the data contained within.

Here AOMEI Partition Assistant Professional Edition is recommended. AOMEI Partition Assistant can restore the lost or deleted partition and protect the data within from damage as long as the data is not overwritten.

Tips:Fast Search” and “Full Search” are two kinds of scanning methods to navigate to your lost partitions. It is recommended to try “Fast Search” first. When it fails, use “Full Search”.

Step 1. Download and start the AOMEI Partition Assistant. Enjoy the features for free in the Demo version.

Step 2. Click “Partition Recovery Wizard” in the toolbar, select the disk that contains the lost SSD partition, then click “Next”.

Step 3. Select “Fast Search”. Then click “Next”.

Step 4. Then your lost SSD partition will be detected. Select the one you want to recover, then click “Proceed”.

This tool always devotes itself to scanning hard disks for deleted partitions. Thus you have easily implemented SSD lost partition recovery.

To sum up

AOMEI Partition Assistant can not only effectively recover lost or deleted partitions on SSD drives or other hard drives, but also migrate operating systems to SSD drives, erase SSD drives, convert basic disks to dynamic disks, or convert dynamic disks.

To perform SSD partition recovery, find out if it is hidden or lost/deleted first, then take the appropriate steps. If it is hidden because of driver letter loss, assign a letter to it; if it is lost somehow or mistakenly deleted, utilize the AOMEI Partition Assistant to solve it.

When seeking approaches to restore deleted or missing data from SSD, instead of trying hard to solve it by yourself, you would better let AOMEI Data Recovery for Windows to help you.

Incidentally, it is sagacious to form a habit of regular data sync and backup to ensure data security. For the sake of time and labor, AOMEI MBackupper can be of great help.
