How to recover data from Synology DiskStation DS2422+ NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Synology DiskStation DS2422+

Synology DiskStation DS2422+ 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 DS2422+.

How to recover data from NAS Synology DiskStation DS2422+

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.

Are there any known limitations or performance issues related to specific RAID levels in NAS Synology DiskStation DS2422+ devices?

There can be limitations or performance issues related to specific RAID levels in NAS Synology DiskStation DS2422+ devices. Here are some factors to consider:

  1. RAID 5 and RAID 6: These RAID levels provide data redundancy and can tolerate the failure of one or two drives respectively. However, they require additional processing power for parity calculations, which may impact performance, especially during write operations.
  2. RAID 1: This RAID level mirrors data across two drives, offering redundancy and improved read performance. However, write performance may be slower compared to other RAID levels as data needs to be written to both drives simultaneously.
  3. RAID 0: This RAID level stripes data across multiple drives, providing improved performance and capacity utilization. However, it does not offer any data redundancy, so if one drive fails, all data is lost.
  4. RAID Expansion: When expanding the RAID array by adding more drives, there can be a performance impact during the expansion process as data is redistributed across the new drives.
  5. Drive Types and Sizes: Mixing different drive types (e.g., HDDs and SSDs) or drive sizes within a RAID array can result in performance inconsistencies or limitations due to differences in speed and capacity.
  6. Network Limitations: The overall performance of a NAS device can also be influenced by network limitations, such as the speed and congestion of the network infrastructure.

It's important to note that the specific performance and limitations can vary depending on the specific configuration, workload, and usage patterns. It's recommended to consult the official documentation or contact Synology support for detailed information regarding the DS2422+ and its RAID performance characteristics.

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

Although NAS DiskStation DS2422+ 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Synology DiskStation DS2422+. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

DiskStation DS2422+ has 12 HDD slots, and it supports the following array types:

  • Synology Hybrid RAID (SHR);
  • RAID 6;
  • RAID 5;
  • RAID 10;
  • RAID 1;
  • RAID 0;
  • Basic;
  • JBOD;

NAS supports:

  • Btrfs;
  • EXT4;
  • EXT3 (External Disk Only);
  • FAT32 (External Disk Only);
  • exFAT (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk Read Only);

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 DS2422+ 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.
