Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Promise often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

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 Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS VSky c100 can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

Power off the NAS and disconnect it from the power source.

WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.
Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.
Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.
Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

Overwriting during the recovery process;
Additional data loss caused by bad sectors;
User errors.

To create a disk image, follow these steps:

Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.
Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

Where Are the User’s Files Actually 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.

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