How to recover data from Promise VTrak M500f 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 VTrak M500f

Promise VTrak M500f NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VTrak M500f.

How to recover data from NAS Promise VTrak M500f

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 the use of deduplication or compression technologies impact data loss risks on NAS Promise VTrak M500f devices?

The use of deduplication or compression technologies can potentially impact data loss risks on NAS Promise VTrak M500f devices.

Deduplication technology eliminates redundant data by storing only unique data blocks and creating references to them. This can reduce storage requirements and increase efficiency. However, if the deduplication process is not implemented correctly or if there are issues with the deduplication algorithm, it can potentially lead to data loss if the references to the unique data blocks are lost or corrupted.

Compression technology reduces the size of data by encoding it in a more compact form. While compression can save storage space and improve performance, there is a risk of data loss if the compression algorithm used is not reliable or if there are errors during the compression process.

It is important to note that the impact of deduplication or compression technologies on data loss risks can vary depending on the specific implementation and configuration of the NAS Promise VTrak M500f devices. It is recommended to carefully evaluate and test these technologies before implementing them in production environments to ensure the integrity and availability of data.

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

Although NAS VTrak M500f 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 VTrak M500f 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.

      Data recovery from a NAS (Network Attached Storage) device can be challenging, especially if the device is experiencing intermittent connectivity issues. However, it is still possible to recover data from such a device depending on the specific circumstances.

      Here are a few steps you can take to attempt data recovery:

      1. Troubleshoot Connectivity Issues: Before attempting data recovery, try to resolve the intermittent connectivity issues. Ensure that all cables are securely connected, restart the device, and check network settings. If possible, connect the NAS directly to a computer to eliminate any network-related issues.
      2. Access Data through Alternate Methods: If the NAS device has multiple interfaces or connectivity options (e.g., USB, eSATA), try accessing the data through an alternate method. This can help bypass the connectivity issues and retrieve the data.
      3. Use Data Recovery Software: If the connectivity issues prevent direct access to the NAS, you can try using data recovery software. Install the software on a computer connected to the same network and attempt to recover data from the NAS. Some data recovery software can scan and recover files even from inaccessible or damaged devices.
      4. Seek Professional Help: If the above steps do not work, or if the data on the NAS is critical and valuable, it is advisable to seek professional data recovery services. Data recovery experts have specialized tools and techniques to recover data from faulty NAS devices. They can disassemble the device, repair any hardware issues, and retrieve the data using specialized methods.

      Remember, in any data recovery scenario, it is crucial to avoid further data loss. Do not attempt to repair or modify the NAS device unless you have the necessary expertise.
