How to recover data from Buffalo TeraStation WS-Q2.0TL/R5 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 Buffalo TeraStation WS-Q2.0TL/R5

Buffalo TeraStation WS-Q2.0TL/R5 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from TeraStation WS-Q2.0TL/R5.

How to recover data from NAS Buffalo TeraStation WS-Q2.0TL/R5

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 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 the NAS Buffalo TeraStation WS-Q2.0TL/R5 device's CPU or processing power affect data transfer and potential loss?

The CPU or processing power of the NAS Buffalo TeraStation WS-Q2.0TL/R5 device can affect data transfer and potential loss in the following ways:

  1. Data Transfer Speed: The CPU's processing power determines how quickly the device can handle data requests and transfer data between the NAS and connected devices. A more powerful CPU can handle data transfers more efficiently, resulting in faster transfer speeds.
  2. Concurrent Connections: The CPU's processing power also affects the number of concurrent connections the NAS device can handle. If the CPU is not powerful enough, it may struggle to handle multiple data transfer requests simultaneously, leading to slower transfer speeds and potential data loss.
  3. Data Integrity and Error Correction: A powerful CPU can handle data integrity checks and error correction more effectively. It can quickly identify and correct errors during data transfer, reducing the chances of data loss or corruption.
  4. RAID Rebuild Times: If the NAS device is configured with RAID (such as RAID 5), a more powerful CPU can significantly reduce the time required for RAID rebuilds. During a RAID rebuild, data from a failed drive is reconstructed onto a new drive. A faster CPU can expedite this process, minimizing the risk of data loss during the rebuild.
  5. Encryption and Compression: Some NAS devices offer encryption and compression features to enhance data security and reduce storage space. These operations can be CPU-intensive. A more powerful CPU can handle encryption and compression tasks more efficiently, ensuring faster data transfer while maintaining data integrity.

In summary, a powerful CPU in the NAS Buffalo TeraStation WS-Q2.0TL/R5 device can improve data transfer speeds, handle concurrent connections effectively, ensure data integrity, reduce RAID rebuild times, and efficiently perform encryption and compression tasks, ultimately minimizing the potential for data loss.

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

Although NAS TeraStation WS-Q2.0TL/R5 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.

TeraStation WS-Q2.0TL/R5 has 4 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • 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 Buffalo TeraStation WS-Q2.0TL/R5 network-attached storage keeps Windows Storage Server 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.
