How to recover data from NAS Buffalo TeraStation TS5400D0404

Buffalo TeraStation TS5400D0404 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 TS5400D0404.

How to recover data from NAS Buffalo TeraStation TS5400D0404

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 deduplication or compression technologies impact data loss risks on NAS Buffalo TeraStation TS5400D0404 devices?

The use of deduplication or compression technologies can potentially impact data loss risks on NAS Buffalo TeraStation TS5400D0404 devices.

Deduplication technology identifies and eliminates duplicate data within a storage system, reducing the amount of data that needs to be stored. This can reduce the risk of data loss as it minimizes the chances of storing multiple copies of the same data. However, it is important to note that deduplication is not a backup solution in itself, and data loss can still occur if there are issues with the storage system or if the deduplication process is not properly implemented.

Compression technology reduces the size of data by encoding it in a more compact form. This can also impact data loss risks as it reduces the amount of storage space required, potentially allowing for more efficient backups and reducing the chances of data loss due to insufficient storage capacity. However, compression can also introduce risks if the compressed data is not properly handled or if there are issues with the compression algorithm itself.

It is crucial to have a comprehensive backup strategy in place to mitigate data loss risks, regardless of whether deduplication or compression technologies are being used. This includes regular backups, off-site storage, and testing of backup and restore processes to ensure data integrity and availability.

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

Although NAS TeraStation TS5400D0404 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS5400D0404. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

TeraStation TS5400D0404 has 4 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • JBOD;

  • 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 TS5400D0404 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.

    Can data recovery from a NAS Buffalo TeraStation TS5400D0404 device be done if the device is experiencing intermittent connectivity issues?
    • Hetman Software

      Yes, data recovery from a NAS Buffalo TeraStation TS5400D0404 device can still be possible even if the device is experiencing intermittent connectivity issues. However, the process may be more challenging and time-consuming.

      Here are a few steps you can take to attempt data recovery:

      1. Troubleshoot the connectivity issues: Try to diagnose and fix the intermittent connectivity problems with the NAS device. This may involve checking network cables, resetting the device, updating firmware, or contacting technical support for assistance.
      2. Use alternative connectivity options: If the NAS device has multiple network ports, try connecting through a different port. You can also try connecting the device directly to a computer using an Ethernet cable to bypass any network-related issues.
      3. Access the NAS device through command-line interface (CLI): Some NAS devices provide a CLI interface that allows you to access and manage the device directly through a command prompt or terminal. If available, this method can help you retrieve data even if the GUI or web interface is not accessible.
      4. Remove the hard drives: If all else fails, you can remove the hard drives from the NAS device and connect them to a computer directly. This will require some technical knowledge and potentially void the warranty, so proceed with caution. Once connected, you can use data recovery software to attempt to recover the files.

      If none of these steps work or if you are uncomfortable performing the data recovery yourself, it is recommended to seek professional assistance from a data recovery service. They have specialized tools and expertise to deal with complex data recovery scenarios, including intermittent connectivity issues.
