How to recover data from Buffalo LinkStation LS-WX2.0TL/R1 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 LinkStation LS-WX2.0TL/R1

Buffalo LinkStation LS-WX2.0TL/R1 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from LinkStation LS-WX2.0TL/R1.

How to recover data from NAS Buffalo LinkStation LS-WX2.0TL/R1

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 a NAS Buffalo LinkStation LS-WX2.0TL/R1 device's cache settings impact data loss risks?

The cache settings on a NAS (Network Attached Storage) device like the Buffalo LinkStation LS-WX2.0TL/R1 can impact data loss risks in the following ways:

  1. Write Cache: The write cache is a temporary storage area where data is held before being written to the actual storage drives. Enabling write cache can improve performance by allowing the device to quickly acknowledge write operations. However, if power is lost or the device crashes before the data is written to the drives, there is a risk of data loss or corruption. Disabling write cache reduces this risk as data is immediately written to the drives.
  2. Read Cache: The read cache stores frequently accessed data in a faster memory or solid-state drive (SSD) to speed up read operations. While read cache generally does not pose a direct risk of data loss, it can potentially serve outdated or corrupted data if not properly synchronized with the actual storage drives. This can result in data inconsistency or errors.
  3. RAID Configuration: The Buffalo LinkStation LS-WX2.0TL/R1 supports various RAID configurations, such as RAID 0, RAID 1, or JBOD. RAID 0, which stripes data across multiple drives for improved performance, increases the risk of data loss as the failure of a single drive can lead to complete data loss. RAID 1, on the other hand, mirrors data across drives for redundancy, reducing the risk of data loss. Choosing the appropriate RAID configuration based on your data protection needs is crucial.
  4. Battery Backup: Some NAS devices, including the Buffalo LinkStation LS-WX2.0TL/R1, offer battery backup units (BBUs) to protect against power outages. BBUs provide temporary power to the device, allowing it to complete pending write operations and ensure data integrity. Enabling and maintaining a functional BBU can significantly reduce the risk of data loss due to sudden power loss.

To minimize data loss risks, it is essential to understand the cache settings and RAID configuration options available on the NAS device, and make informed choices based on your specific requirements for performance, data redundancy, and data protection. Additionally, implementing regular backups and following best practices for data storage and security can further mitigate the risk of data loss.

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

Although NAS LinkStation LS-WX2.0TL/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.

Where are user’s files stored?

The Buffalo LinkStation LS-WX2.0TL/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.

      Data recovery from a NAS Buffalo LinkStation LS-WX2.0TL/R1 device should not affect the existing data if done correctly. However, it is always recommended to take precautionary measures and follow best practices to minimize the risk of data loss or corruption during the recovery process.

      Here are a few tips to ensure a safe data recovery process:

      1. Avoid writing new data to the NAS device: Do not save or modify any data on the NAS while attempting to recover the lost data. This helps prevent overwriting the existing data and increases the chances of successful recovery.
      2. Use a separate storage device for recovery: Connect a separate storage device (such as an external hard drive) to the NAS and recover the lost data onto that device. This way, you can keep the existing data on the NAS untouched.
      3. Follow proper data recovery procedures: Use reliable data recovery software or consult a professional data recovery service to perform the recovery process. Follow the instructions provided by the software or service carefully to ensure the best possible outcome.
      4. Create a backup before attempting recovery: If possible, create a backup of the NAS data before attempting any recovery. This ensures that even if something goes wrong during the recovery process, you have a copy of the data to fall back on.

      Remember, data recovery can be a complex process, and there is always a small risk of data loss or corruption. It is advisable to consult a professional data recovery service if the data on your NAS is critical or valuable.
