How to recover data from Promise VSky s410 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 Promise VSky s410

Promise VSky s410 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VSky s410.

How to recover data from NAS Promise VSky s410

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 Promise also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can device firmware rollback or downgrading impact data loss risks for NAS Promise VSky s410 devices?

Yes, device firmware rollback or downgrading can potentially impact data loss risks for NAS Promise VSky s410 devices. When you rollback or downgrade the firmware, you are essentially reverting to an older version of the software that may not have the same level of stability, bug fixes, or security patches as the latest firmware version.

This can introduce potential vulnerabilities or compatibility issues that could lead to data loss or corruption. It is always recommended to keep your firmware up to date to ensure the best performance, stability, and security for your NAS device.

If you are considering rolling back or downgrading the firmware, it is crucial to backup all your important data before proceeding. This way, if any issues arise during the process or after the downgrade, you can restore your data from the backup and minimize the risk of data loss.

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

Although NAS VSky s410 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 Promise VSky s410 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.

    Can data recovery from a NAS Promise VSky s410 device be done if the device is showing signs of network congestion or bandwidth issues?
    • Hetman Software

      Data recovery from a NAS (Network Attached Storage) device like the Promise VSky s410 can still be possible even if the device is experiencing network congestion or bandwidth issues. However, the process might be slower or more challenging due to the limited network resources.

      Here are a few considerations:

      1. Network congestion: If the NAS device is connected to a congested network, it might result in slower data transfer speeds or intermittent connectivity. This can make the data recovery process time-consuming. You may need to be patient and allow the recovery software or tools to work through the network limitations.
      2. Bandwidth issues: Limited bandwidth can affect the speed at which data can be transferred from the NAS device to the recovery destination. It might be helpful to schedule the recovery process during off-peak hours when network usage is lower. Additionally, you can try prioritizing the data recovery traffic by adjusting quality of service (QoS) settings on your network router or switch.
      3. Local recovery options: If network congestion is a significant issue, you could consider connecting directly to the NAS device using a physical connection like Ethernet or USB. This can bypass the network congestion and allow for faster data recovery. However, this option might require technical expertise or assistance.
      4. Seek professional help: If you are unsure about performing data recovery yourself or if the network congestion persists, it is advisable to consult a professional data recovery service. They have specialized tools and expertise to handle complex recovery scenarios and can work around network limitations.

      Remember to avoid making any changes to the NAS device or its configuration before attempting data recovery, as it may further complicate the process.
