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 Level One also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Are there any common mistakes or oversights made by users that can lead to data loss on NAS Level One GNS-1001 devices?

While I couldn't find specific information about common mistakes or oversights that can lead to data loss on NAS Level One GNS-1001 devices, there are some general practices that users should be aware of to prevent data loss on any NAS device. Here are a few potential mistakes or oversights that can lead to data loss:

  1. Lack of backups: Not having a proper backup strategy is one of the most common mistakes. If the NAS device fails or data gets corrupted, having a backup ensures you can restore your data.
  2. Inadequate RAID configuration: NAS devices often support RAID for data redundancy and protection against drive failures. If the RAID configuration is not set up correctly or not monitored regularly, it can lead to data loss.
  3. Power outages or improper shutdowns: Abrupt power loss or improper shutdowns can cause data corruption or damage to the NAS device. Users should ensure the NAS is connected to a reliable power source and follow proper shutdown procedures.
  4. Neglecting firmware updates: Not keeping the NAS firmware up to date can lead to security vulnerabilities or compatibility issues, which can ultimately result in data loss.
  5. Insufficient security measures: Weak passwords, improper user access controls, or enabling unnecessary network services can make the NAS device vulnerable to unauthorized access or malware attacks, potentially leading to data loss.

To mitigate these risks, it is advisable to regularly back up data, configure RAID properly, use a reliable power source, keep the firmware updated, and implement strong security measures. Additionally, consulting the user manual or seeking support from the manufacturer can provide specific guidance on avoiding data loss on the NAS Level One GNS-1001 device.

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

Although NAS GNS-1001 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.
