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 improper network configuration or firewall settings result in data loss on NAS Promise VSky c100 devices?

Yes, improper network configuration or firewall settings can potentially result in data loss on NAS Promise VSky c100 devices.

If the network configuration is not properly set up, it can lead to connectivity issues between the NAS device and other devices on the network. This can result in data loss if the NAS is unable to communicate with the devices that are supposed to access or store data on it.

Similarly, if the firewall settings are not correctly configured, it can block necessary network traffic to and from the NAS device. This can prevent data from being transferred to or from the NAS, potentially leading to data loss.

It is important to ensure that proper network configuration and firewall settings are in place to avoid any potential data loss on NAS devices.

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

Although NAS VSky c100 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 VSky c100. 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.

VSky c100 has 3 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 1E;
  • JBOD;

NAS supports:

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

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 c100 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.

    How does data recovery from NAS Promise VSky c100 differ from other storage devices?
    • Hetman Software
      Hetman Software 7.09.2023 16:00 #

      Data recovery from NAS Promise VSky C100 is different from other storage devices in several ways:

      1. RAID Configuration: The Promise VSky C100 is a network-attached storage (NAS) device that typically uses RAID configurations for data redundancy and performance improvement. Data recovery from a Promise VSky C100 involves understanding the specific RAID configuration used, such as RAID 0, RAID 1, RAID 5, or RAID 6.
      2. Proprietary Software: Promise VSky C100 uses its own proprietary software for managing the NAS system. This software may have unique features and functionalities that differ from other storage devices. Data recovery specialists need to be familiar with this software to effectively recover data from the device.
      3. Distributed Architecture: The Promise VSky C100 is designed with a distributed architecture, which means that data is spread across multiple drives or nodes in the system. This architecture enhances performance and fault tolerance but also adds complexity to data recovery. Specialists need to understand the distributed architecture and the interdependencies between the nodes to recover the data successfully.
      4. Data Striping and Parity: RAID configurations in Promise VSky C100 often involve data striping and parity techniques. Data striping divides data into blocks and distributes them across multiple drives, while parity information is used for error detection and recovery. Recovering data from such configurations requires specialized knowledge and tools to reconstruct the data from the striped blocks and parity information.
      5. Vendor-Specific Challenges: Each storage device manufacturer may have its own unique challenges and intricacies in data recovery. Promise VSky C100 is no exception. Specialists need to be familiar with the specific challenges associated with this device, such as compatibility issues, firmware limitations, or proprietary file systems.

      Overall, data recovery from NAS Promise VSky C100 requires expertise in RAID configurations, distributed architectures, proprietary software, and vendor-specific challenges. It is recommended to consult professional data recovery services with experience in recovering data from Promise VSky C100 or similar storage devices.
