How to recover data from NAS Buffalo TeraStation TS5810DN3204

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.

Can the use of specific backup and recovery strategies help reduce potential data loss risks on NAS Buffalo TeraStation TS5810DN3204 devices?

Yes, the use of specific backup and recovery strategies can help reduce potential data loss risks on NAS Buffalo TeraStation TS5810DN3204 devices. Here are some strategies that can be employed:

  1. Regular backups: Implement a regular backup schedule to ensure that important data is regularly copied and stored in a separate location. This can be done using built-in backup software or third-party backup solutions.
  2. Offsite backups: Store backups in an offsite location or cloud storage to protect against physical damage or theft of the NAS device. This ensures that even if the NAS is compromised, the data can still be recovered from the offsite backup.
  3. RAID configuration: Set up the TeraStation in a RAID configuration, such as RAID 1 or RAID 5, to provide redundancy and protect against data loss in case of drive failures. RAID allows for automatic rebuilding of data on a new drive when a failure occurs.
  4. Redundant power supply: Use a NAS device with a redundant power supply to minimize the risk of data loss due to power supply failures. Redundant power supplies provide backup power in case one fails, ensuring uninterrupted operation of the device.
  5. Uninterruptible Power Supply (UPS): Connect the NAS device to a UPS to protect against power outages and ensure a safe shutdown in case of extended power loss. This helps prevent data corruption and loss due to sudden power failures.
  6. Regular firmware updates: Keep the NAS device's firmware up to date to benefit from bug fixes, security patches, and performance improvements. This helps protect against potential vulnerabilities that could lead to data loss.
  7. User access controls: Implement proper user access controls and permissions to prevent unauthorized access and accidental deletion of data. This ensures that only authorized users can modify or delete data, reducing the risk of data loss.

By implementing these backup and recovery strategies, the potential risks of data loss on NAS Buffalo TeraStation TS5810DN3204 devices can be significantly reduced.

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

Although NAS TeraStation TS5810DN3204 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.
