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 improper configuration of network settings or IP addresses result in data loss on NAS Buffalo TeraStation TS-I1.0TGL/R5 devices?

Yes, improper configuration of network settings or IP addresses can potentially result in data loss on NAS Buffalo TeraStation TS-I1.0TGL/R5 devices. If the network settings or IP addresses are not correctly configured, it may lead to connectivity issues, loss of access to the NAS device, or even data corruption. It is important to ensure that network settings and IP addresses are properly configured to avoid any potential data loss or other issues.

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

Although NAS TeraStation TS-I1.0TGL/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.

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 TS-I1.0TGL/R5 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.

      Yes, there are specific techniques used in data recovery from NAS Buffalo TeraStation TS-I1.0TGL/R5 devices with RAID configurations. Here are some of the common techniques:

      1. Rebuilding RAID Array: If one or more drives in the RAID array have failed, the first step is to replace the failed drives and rebuild the RAID array. This can be done using the NAS device's management software or through the device's firmware.
      2. Data Reconstruction: In cases where the RAID array is intact but data is inaccessible or corrupted, data reconstruction techniques are used. This involves analyzing the RAID configuration, identifying the correct order of the drives, and reconstructing the data using specialized software.
      3. Data Extraction: If the RAID array is severely damaged or corrupted, data extraction techniques may be used. This involves removing the drives from the NAS device and connecting them to a specialized data recovery tool or hardware. The tool then reads the data directly from the drives and extracts it.
      4. File Carving: In situations where the file system is damaged or deleted, file carving techniques can be employed. This involves scanning the raw data on the drives and searching for file signatures or patterns to recover individual files.

      It's important to note that data recovery from NAS devices with RAID configurations can be complex and should ideally be performed by professional data recovery services with experience in handling such devices.
