How to recover data from NAS Buffalo TeraStation TS3210DN0402

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 power outages or surges affect data stored in NAS Buffalo TeraStation TS3210DN0402 devices?

Yes, power outages or surges can potentially affect the data stored in NAS Buffalo TeraStation TS3210DN0402 devices. Power outages can cause the NAS device to shut down abruptly, leading to data corruption or loss if the device is not properly configured with backup power or a UPS (Uninterruptible Power Supply). Power surges, on the other hand, can cause damage to the NAS device's internal components, including hard drives, which can result in data loss or hardware failure. It is recommended to have appropriate power protection measures in place, such as using a UPS and surge protectors, to minimize the risk of data loss or damage during power-related events. Additionally, regular backups of the data stored on the NAS device should be performed to ensure data redundancy and recovery options in case of any unforeseen events.

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

Although NAS TeraStation TS3210DN0402 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.
