How to recover data from Promise VTrak M500p 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 M500p

Promise VTrak M500p 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 M500p.

How to recover data from NAS Promise VTrak M500p

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.

How can a NAS Promise VTrak M500p device's cache settings impact data loss risks?

The cache settings of a NAS Promise VTrak M500p device can impact data loss risks in the following ways:

  1. Write-back vs. Write-through cache mode: The device may offer the option to configure its cache in either write-back or write-through mode. In write-back mode, data is initially written to the cache and then asynchronously written to the disk. This can improve performance but increases the risk of data loss in case of a power outage or system failure before the data is written to the disk. In write-through mode, data is immediately written to the disk, reducing the risk of data loss but potentially impacting performance.
  2. Cache size: The size of the cache in the device can also impact data loss risks. A larger cache can improve performance by allowing more data to be temporarily stored in memory before being written to the disk. However, if the cache is not properly protected, a power failure or system crash can result in data loss if the data in the cache has not been written to the disk.
  3. Cache protection mechanisms: The device may offer various cache protection mechanisms to reduce the risk of data loss. For example, it may have a battery backup unit (BBU) that can provide power to the cache in case of a power outage, allowing data to be safely written to the disk. It may also have features like cache mirroring or RAID protection to ensure redundancy and data integrity in case of a cache failure.
  4. Proper configuration and monitoring: It is crucial to properly configure and monitor the cache settings of the device to minimize data loss risks. This includes ensuring that the cache is adequately protected, regularly checking the status of the cache, and implementing appropriate backup and disaster recovery strategies to mitigate the impact of any potential data loss.

In summary, the cache settings of a NAS Promise VTrak M500p device can significantly impact data loss risks. It is vital to carefully consider the write-back/write-through mode, cache size, cache protection mechanisms, and proper configuration and monitoring to ensure data integrity and minimize the chances of data loss.

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

Although NAS VTrak M500p 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 Promise VTrak M500p. 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.

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 M500p 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 VTrak M500p device be performed if there are issues with the network interface card or port?
    • Hetman Software
      Hetman Software 8.09.2023 10:59 #

      Yes, data recovery from a NAS Promise VTrak M500p device can still be performed even if there are issues with the network interface card or port.

      In such cases, you can try the following steps:

      1. Check for physical issues: Ensure that the network cable is properly connected and not damaged. Try using a different cable or port to rule out any physical issues with the network connection.
      2. Use a different network interface: If the network interface card is faulty, you can try using a different network interface card or port on the NAS device. Some NAS devices have multiple network interfaces, so you can switch to a different one.
      3. Direct connection: If the NAS device supports it, you can directly connect it to a computer using an Ethernet cable. This bypasses the network interface card and allows you to access the data directly from the NAS.
      4. Data recovery software: If none of the above options work, you can use data recovery software that supports NAS devices. Connect the NAS device directly to a computer and use the software to scan and recover the data from the NAS.
      5. Professional data recovery services: If you are unable to recover the data yourself, you can seek the help of professional data recovery services. They have specialized tools and expertise to recover data from faulty NAS devices, including those with network interface issues.

      It is important to note that if the NAS device itself has hardware failures or the data is encrypted, the recovery process may be more complex and require professional assistance.
