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 Buffalo 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 a NAS Buffalo TeraStation TS-WVH4.0TL/R1 device's power management settings impact data availability and potential loss?

The power management settings of a NAS Buffalo TeraStation TS-WVH4.0TL/R1 device can impact data availability and potential loss in the following ways:

  1. Sleep Mode: If the device is set to enter sleep mode after a certain period of inactivity, it can lead to data unavailability during that time. When the device is in sleep mode, it may not respond to network requests or access requests from connected devices. If critical data is needed during this period, it may not be accessible, leading to potential loss.
  2. Drive Spin Down: The NAS device may have a setting to spin down the hard drives after a period of inactivity. While this can save power, it can also introduce delays when accessing data. When a drive is spun down, it takes time to spin up and become ready for data access. If data is needed urgently, this delay can impact availability and productivity.
  3. Power Interruptions: Power management settings can also impact data availability during power interruptions. If the device is set to shut down or enter a low-power state during a power outage, data may not be accessible until power is restored and the device is fully operational again. This can lead to potential data loss if critical operations were ongoing during the power interruption.
  4. Scheduled Power On/Off: Some NAS devices allow scheduling the power on and power off times. If the device is set to turn off during non-working hours, it can impact data availability during that time. If users or applications require access to data during the scheduled power-off period, it may not be available, leading to potential loss.

To mitigate the impact on data availability and potential loss, it is important to carefully configure the power management settings of the NAS device. It is recommended to balance power-saving requirements with the need for continuous data access. Regular backups and redundancy measures should also be implemented to minimize the risk of data loss during any potential downtime.

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

Although NAS TeraStation TS-WVH4.0TL/R1 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 Buffalo TeraStation TS-WVH4.0TL/R1 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.

      To prevent data recovery from a NAS Buffalo TeraStation TS-WVH4.0TL/R1 device in the future, you can take the following measures:

      1. Implement strong access controls: Set up strong passwords for all user accounts and regularly change them. Disable default accounts and create individual accounts with appropriate access privileges. Limit access to only authorized users.
      2. Enable encryption: Utilize the encryption feature provided by the NAS device. This ensures that even if the physical drives are stolen, the data remains encrypted and inaccessible without the encryption key.
      3. Regularly update firmware: Keep the NAS firmware up to date to ensure that any security vulnerabilities are patched. Regularly check for updates from the manufacturer's website or enable automatic updates if available.
      4. Implement network security measures: Secure your network by using strong Wi-Fi passwords, enabling network encryption (WPA2 or higher), and disabling remote access if not required. Regularly monitor network traffic and enable firewalls to prevent unauthorized access.
      5. Regularly backup data: Implement a robust backup strategy by regularly backing up the data stored on the NAS to an external storage device or a cloud-based backup service. This ensures that even if the NAS is compromised, you can still recover your important data from backups.
      6. Physical security: Protect the physical NAS device by placing it in a secure location, such as a locked server room or cabinet, to prevent unauthorized access or theft.
      7. Educate users: Train users on best practices for data security, such as avoiding suspicious emails or links that could lead to malware infections. Encourage them to use strong passwords and be cautious while accessing the NAS device from external networks.
      8. Regularly monitor and log activities: Enable logging features on the NAS device to track and monitor user activities. Regularly review these logs to identify any suspicious or unauthorized access attempts.

      By implementing these preventive measures, you can enhance the security of your NAS Buffalo TeraStation device and reduce the risk of data recovery by unauthorized individuals.
