How to recover data from NAS Synology SA3600

Synology SA3600 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from SA3600.

How to recover data from NAS Synology SA3600

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.

What is a NAS Synology SA3600 (Network Attached Storage) device?

The Synology SA3600 is a Network Attached Storage (NAS) device manufactured by Synology Inc. It is a high-performance storage solution designed for enterprise-level businesses.

The SA3600 offers versatile storage capabilities, allowing businesses to store, manage, and protect their data effectively. It features a 12-bay design, supporting both 3.5-inch and 2.5-inch SATA drives, providing a large storage capacity. It also supports SSD caching for improved performance.

The device is powered by a powerful Intel Xeon processor and has a large memory capacity, enabling it to handle demanding workloads and multiple concurrent users. It offers high-speed connectivity options such as multiple Gigabit Ethernet ports and PCIe expansion slots for adding additional network cards or storage expansion units.

The SA3600 runs on Synology's DiskStation Manager (DSM) operating system, which provides a user-friendly interface for managing and configuring the NAS. DSM offers a wide range of features, including data backup and synchronization, file sharing, multimedia streaming, and comprehensive security options.

Overall, the Synology SA3600 is a robust and scalable NAS solution suitable for businesses that require high-performance storage and advanced data management capabilities.

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

Although NAS SA3600 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 SA3600. 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.

SA3600 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 SA3600 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.

  • In what ways does a NAS Synology SA3600 provide better data security and protection than regular external hard drives?

    The Synology SA3600 NAS (Network Attached Storage) provides several advantages in terms of data security and protection compared to regular external hard drives. Some of these include:

    1. Redundancy and data protection: The SA3600 supports various RAID configurations, allowing you to create redundant arrays of hard drives. This means that even if one or more drives fail, your data remains accessible and protected. In contrast, regular external hard drives typically do not offer any redundancy, leaving your data vulnerable to loss in case of drive failure.
    2. Data backup and replication: The SA3600 offers built-in backup and replication features, allowing you to create scheduled backups of your data to other NAS devices, remote servers, or cloud storage services. This ensures that even if your primary storage fails or gets damaged, you have an additional copy of your data for recovery. External hard drives usually require manual backup processes and lack automated replication capabilities.
    3. Advanced security features: The SA3600 provides various security features such as AES 256-bit encryption, firewall, network intrusion detection, and prevention systems. These features help protect your data from unauthorized access, malware, and other external threats. Regular external hard drives typically lack such advanced security measures.
    4. User access controls: The SA3600 allows you to set up user access controls and permissions, ensuring that only authorized individuals can access specific files or folders. This helps prevent accidental or intentional data deletion or modification. External hard drives generally do not offer granular user access controls.
    5. Scalability and expandability: The SA3600 is designed to be scalable, allowing you to easily expand storage capacity by adding additional hard drives or attaching expansion units. This ensures that your storage needs can grow with your data requirements. Regular external hard drives have fixed storage capacities and are not easily expandable.
    6. Centralized management: The SA3600 provides a centralized management interface, allowing you to manage and monitor multiple storage devices from a single dashboard. This simplifies administration and makes it easier to ensure data security and protection across your network. External hard drives are typically managed individually, which can be time-consuming and less efficient.

    Overall, the Synology SA3600 NAS offers a comprehensive set of features and capabilities that enhance data security and protection compared to regular external hard drives.
