Buffalo TeraStation TS-RI8.0TGL/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 TS-RI8.0TGL/R5.

How to recover data from NAS Buffalo TeraStation TS-RI8.0TGL/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.

Are there any data storage capacity limitations that can impact data loss risks for NAS Buffalo TeraStation TS-RI8.0TGL/R5 devices?

Yes, there are data storage capacity limitations that can impact data loss risks for NAS Buffalo TeraStation TS-RI8.0TGL/R5 devices. The specific limitations and risks depend on various factors such as the RAID configuration, hard drive capacity, and the overall design of the device.

Some potential limitations and risks include:

  1. RAID configuration: The TeraStation TS-RI8.0TGL/R5 supports RAID levels 0, 1, 5, 10, and JBOD. Each RAID level has its own advantages and limitations. For example, RAID 0 offers improved performance but provides no data redundancy, so a single drive failure can result in complete data loss. RAID 5 provides data redundancy but has a higher risk of data loss during a drive rebuild due to the large capacity drives used in the TS-RI8.0TGL/R5.
  2. Hard drive capacity: The TeraStation TS-RI8.0TGL/R5 supports up to eight hard drives, with a maximum capacity of 8TB per drive, resulting in a total capacity of 64TB. As the capacity of individual drives increases, the time required to rebuild a failed drive also increases. During this rebuild process, there is an increased risk of data loss if another drive fails or if there are errors in the rebuild process.
  3. Device design and firmware: The design and firmware of the TeraStation TS-RI8.0TGL/R5 can also impact data loss risks. The device may have limitations in terms of file system support, maximum file size, or maximum number of files. Additionally, firmware bugs or vulnerabilities can potentially lead to data loss if not addressed through regular firmware updates.

To mitigate data loss risks, it is recommended to regularly backup the data stored on the TeraStation TS-RI8.0TGL/R5 to an external storage device or cloud storage. Implementing a suitable RAID level and regularly monitoring the health of the hard drives can also help minimize the risk of data loss.

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

Although NAS TeraStation TS-RI8.0TGL/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.
