How to recover data from Instek NR5400-1U 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 Instek NR5400-1U

Instek NR5400-1U NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from NR5400-1U.

How to recover data from NAS Instek NR5400-1U

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 Instek 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 conducting regular backups on external storage devices mitigate data loss risks for NAS Instek NR5400-1U devices?

Conducting regular backups on external storage devices can mitigate data loss risks for NAS Instek NR5400-1U devices in the following ways:

  1. Redundancy: By creating backups on external storage devices, you ensure that there is a duplicate copy of your data. This redundancy reduces the risk of data loss in case of hardware failures, such as hard drive crashes or system malfunctions.
  2. Protection against physical damage: External storage devices can be stored in different physical locations, away from the primary NAS device. This safeguards your data against physical damage, such as fire, flood, or theft, which could otherwise result in complete data loss.
  3. Protection against malware and ransomware: If your NAS device gets infected with malware or ransomware, your data can be compromised or encrypted, leading to potential loss. Regularly backing up your data on external storage devices ensures that you have clean copies of your data that can be restored in case of an attack.
  4. Version control and data recovery: Regular backups allow you to maintain multiple versions of your data. In case of accidental deletion, file corruption, or data modification, you can restore a previous version from the backup, minimizing the impact of data loss.
  5. Quick recovery: If data loss occurs on the NAS device, having backups on external storage devices enables faster recovery. Instead of starting from scratch, you can restore the data from the backups, reducing downtime and minimizing the impact on your operations.
  6. Offline storage: External storage devices can be disconnected from the network after the backup process, providing an additional layer of security. This prevents data from being accessed or compromised by unauthorized users or external threats.

To maximize the effectiveness of backups, it is recommended to follow best practices such as maintaining multiple copies of backups, testing the restoration process periodically, and ensuring the external storage devices are properly maintained and protected.

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

Although NAS NR5400-1U 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.

NR5400-1U has 2 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

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 Instek NR5400-1U network-attached storage keeps OS Linux 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.

      To prevent data recovery from a NAS Instek NR5400-1U device in the future, you can take the following measures:

      1. Encryption: Enable encryption on your NAS device. This ensures that even if someone gains unauthorized access to the physical drives, the data remains encrypted and inaccessible without the decryption key.
      2. Secure access: Implement strong authentication mechanisms such as complex passwords, two-factor authentication (2FA), or biometric authentication to prevent unauthorized access to the NAS device.
      3. Regular backups: Regularly backup your data to an offsite location or cloud storage. This ensures that even if the NAS device fails or data is compromised, you have a copy of your important data.
      4. Firmware and software updates: Keep the firmware and software of your NAS device up to date. Manufacturers often release updates to fix security vulnerabilities, so regularly applying these updates helps protect against potential exploits.
      5. Network security: Secure your network to prevent unauthorized access to the NAS device. Use firewalls, intrusion detection systems, and keep your network equipment updated with the latest security patches.
      6. Physical security: Ensure physical security of the NAS device by placing it in a locked room or cabinet. Limit access to authorized personnel only and monitor any physical access to the device.
      7. User access control: Implement proper user access controls and permissions. Restrict access to sensitive data to only those who require it. Regularly review and revoke unnecessary access rights.
      8. Data wiping: When decommissioning or disposing of a NAS device, ensure that all data is securely wiped from the drives. Use specialized data erasure tools or physically destroy the drives to prevent any possibility of data recovery.
      9. Monitoring and logging: Enable logging and monitoring features on the NAS device to detect any suspicious activities or unauthorized access attempts. Regularly review the logs to identify potential security incidents.
      10. Employee education: Train your employees on best practices for data security, including the importance of strong passwords, avoiding phishing attempts, and being cautious about sharing sensitive information.

      By implementing these preventive measures, you can significantly reduce the risk of data recovery from a NAS device like the Instek NR5400-1U in the future.
