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 remote access to NAS Promise Pegasus2 R8 devices pose additional data loss risks?

Remote access to NAS (Network Attached Storage) devices, including the Promise Pegasus2 R8, can pose potential data loss risks if not properly secured and managed. Here are some considerations:

  1. Security vulnerabilities: Remote access can introduce security vulnerabilities if not properly configured. If unauthorized individuals gain access to the device, they may be able to delete or modify data, or even steal sensitive information.
  2. Weak passwords: Weak or easily guessable passwords can make it easier for attackers to gain unauthorized access to the NAS device. It is crucial to use strong, unique passwords and enable two-factor authentication if available.
  3. Network vulnerabilities: If the network used for remote access is not secure, it may be susceptible to attacks like man-in-the-middle or eavesdropping. It is recommended to use secure protocols like SSH or VPN to establish remote connections.
  4. Firmware and software updates: Regularly updating the firmware and software of the NAS device is important to patch any security vulnerabilities. Failure to do so may expose the device to potential exploits.
  5. Data backup and redundancy: Remote access does not inherently increase data loss risks, but it is essential to have proper backup and redundancy measures in place. This ensures that even if data is accidentally deleted or lost due to remote access issues, it can be recovered from backups.
  6. User error: Remote access can increase the likelihood of user error leading to data loss. Accidental deletion, formatting, or modification of data can occur if users are not cautious or lack proper training.

To mitigate these risks, it is crucial to follow best practices for securing remote access, such as using strong passwords, enabling encryption, updating firmware and software, and regularly backing up data. Additionally, implementing access controls and monitoring solutions can help detect and prevent unauthorized access attempts.

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

Although NAS Pegasus2 R8 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.
