How to recover data from Netgear ReadyNAS RR3312 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 Netgear ReadyNAS RR3312

Netgear ReadyNAS RR3312 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from ReadyNAS RR3312.

How to recover data from NAS Netgear ReadyNAS RR3312

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 Netgear 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 preventive measures to minimize the risk of data loss on NAS Netgear ReadyNAS RR3312 devices?

Yes, there are several preventive measures you can take to minimize the risk of data loss on NAS Netgear ReadyNAS RR3312 devices:

  1. Regular backups: Implement a regular backup strategy to ensure your data is safely stored in another location. Consider using a cloud backup service or an external hard drive for additional redundancy.
  2. RAID configuration: Set up your ReadyNAS device in a RAID configuration (such as RAID 1 or RAID 5) to provide data redundancy and protect against drive failures. This way, if one drive fails, your data will still be accessible from the remaining drives.
  3. UPS (Uninterruptible Power Supply): Connect your ReadyNAS device to a UPS to protect it from sudden power outages or surges. This will help prevent data corruption or loss due to unexpected power interruptions.
  4. Firmware updates: Regularly check for and install firmware updates provided by Netgear. These updates often include security patches and bug fixes that can help protect your device from vulnerabilities.
  5. User access control: Implement strong user access control measures, such as strong passwords and two-factor authentication, to prevent unauthorized access to your ReadyNAS device.
  6. Antivirus and firewall: Install and regularly update antivirus software on your ReadyNAS device to protect against malware and other threats. Additionally, configure a firewall to control incoming and outgoing network traffic.
  7. Physical security: Ensure that your ReadyNAS device is stored in a secure location, preferably in a locked room or cabinet, to prevent physical theft or tampering.
  8. Regular maintenance: Perform regular maintenance tasks, such as checking hard drive health, monitoring system logs, and cleaning dust from the device, to ensure optimal performance and prevent potential issues.

By implementing these preventive measures, you can significantly reduce the risk of data loss on your NAS Netgear ReadyNAS RR3312 device.

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

Although NAS ReadyNAS RR3312 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.

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 Netgear ReadyNAS RR3312 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.

      Yes, it is possible to recover data from a NAS Netgear ReadyNAS RR3312 device that has been affected by a controller card failure or interface problem. However, the process of data recovery can be complex and may require the assistance of a professional data recovery service.

      In such cases, the first step is to diagnose the exact cause of the failure. If it is determined that the controller card has failed or there is an interface problem, the next step is to replace the faulty component. This may involve sourcing a new controller card or repairing the existing one.

      Once the hardware issue is resolved, the data recovery process can begin. This typically involves connecting the NAS device to a computer or another compatible device and using specialized data recovery software to extract the data from the drives. In some cases, the data recovery service may need to rebuild the RAID array or repair any corrupted data.

      It is important to note that attempting to recover data from a failed NAS device without proper knowledge and experience can lead to further damage or data loss. Therefore, it is recommended to seek professional assistance from a reputable data recovery service in such situations.
