How to recover data from NAS Synology DiskStation DS213+ / DS213 / DS213j / DS213air

Synology DiskStation DS213+ / DS213 / DS213j / DS213air NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from DiskStation DS213+ / DS213 / DS213j / DS213air.

How to recover data from NAS Synology DiskStation DS213+ / DS213 / DS213j / DS213air

Recover data from damaged RAID arrays inaccessible from a computer.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Synology also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can data be recovered from a NAS Synology DiskStation DS213+ / DS213 / DS213j / DS213air device after a malfunction or data loss event?

To recover data from a malfunctioning or data loss event on a Synology DiskStation DS213+ / DS213 / DS213j / DS213air device, you can follow these steps:

  1. Identify the cause of the malfunction: Determine whether the issue is related to hardware failure, software corruption, or accidental data deletion. This will help you choose the appropriate recovery method.
  2. Contact Synology Support: If your device is still under warranty or you have an active support contract, reach out to Synology Support for assistance. They can guide you through the recovery process or provide recommendations based on your specific situation.
  3. Check for backup: If you have a backup of your data, you can restore it to the NAS device. Synology DiskStation devices offer various backup options, including local backups to external drives or remote backups to cloud services. Refer to the Synology documentation for instructions on how to restore data from a backup.
  4. Use data recovery software: If you don't have a backup or the backup is incomplete, you can try using data recovery software specifically designed for NAS devices. Some popular options include DiskGenius, R-Studio, and EaseUS Data Recovery Wizard. Install the software on a separate computer and connect the malfunctioning NAS device to it. Follow the software instructions to scan for recoverable data and attempt to recover it.
  5. Seek professional data recovery services: If the above methods fail or you are dealing with severe data loss due to physical damage or RAID failure, it is recommended to seek professional data recovery services. Contact a reputable data recovery company with experience in NAS devices. They have specialized tools and expertise to recover data from damaged or failed NAS devices.

Remember, in any data loss situation, it is crucial to avoid further writes or modifications to the affected NAS device to prevent overwriting the lost data.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS DiskStation DS213+ / DS213 / DS213j / DS213air can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The Synology DiskStation DS213+ / DS213 / DS213j / DS213air network-attached storage keeps DSM (DiskStation Manager) operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.
