How to recover data from Promise Pegasus R6 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 Pegasus R6

Promise Pegasus R6 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from Pegasus R6.

How to recover data from NAS Promise Pegasus R6

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 software bugs or glitches impact data integrity on NAS Promise Pegasus R6 devices?

Software bugs or glitches can impact data integrity on NAS Promise Pegasus R6 devices in several ways:

  1. Data corruption: Bugs or glitches in the software can lead to data corruption, where the information stored on the device becomes unreadable or unusable. This can result in the loss of important files or data.
  2. Data loss: In some cases, software bugs or glitches can cause data loss by deleting or overwriting files unintentionally. This can happen due to issues like improper handling of file systems, incorrect data synchronization, or faulty data recovery mechanisms.
  3. Incomplete or inaccurate data transfers: Bugs or glitches can cause incomplete or inaccurate data transfers between the NAS device and other connected devices. This can result in missing or incorrect data, leading to data integrity issues.
  4. File system errors: Software bugs can also lead to file system errors on the NAS device. These errors can make it difficult to access or modify files, and in some cases, can cause data loss or corruption.
  5. Performance degradation: Some software bugs or glitches can impact the overall performance of the NAS device. This can result in slow data transfer speeds, increased latency, or unresponsive behavior, affecting data integrity by making it difficult to access or modify files reliably.

To mitigate the impact of software bugs or glitches on data integrity, it is essential to regularly update the NAS device's firmware and software to the latest versions provided by the manufacturer. Additionally, implementing proper backup strategies, such as regular data backups to external storage or cloud services, can help protect against potential data loss or corruption.

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

Although NAS Pegasus R6 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.

Pegasus R6 has 6 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 1E;
  • RAID 3;
  • RAID 5;
  • RAID 6;
  • JBOD;

NAS supports:

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

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 Pegasus R6 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.
