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 network configuration or firewall settings result in data loss on NAS Buffalo TeraStation TS-6VHL/E devices?

Yes, improper network configuration or firewall settings can potentially result in data loss on NAS Buffalo TeraStation TS-6VHL/E devices. Here are a few scenarios where this could occur:

  1. Network misconfiguration: If the network settings on the TeraStation are not properly configured, it may not be able to connect to the network or may experience intermittent connectivity issues. This can lead to data loss if the device is unable to access or save data to the network.
  2. Firewall blocking access: If the firewall settings on the TeraStation or the network are too restrictive, it may block necessary network traffic required for data transfer. This can prevent the device from accessing or transferring data, resulting in potential data loss.
  3. Inadequate security measures: If the firewall settings are too lenient or if the TeraStation is not properly secured, it may become vulnerable to unauthorized access or attacks. This could potentially lead to data loss if the device is compromised or if malicious actors gain unauthorized access to the data stored on the device.

To mitigate the risk of data loss due to network configuration or firewall issues, it is important to ensure that the TeraStation is properly configured, network settings are accurate, and firewall rules are appropriately set to allow necessary network traffic. Regularly updating the firmware and implementing strong security measures can also help protect against potential data loss.

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

Although NAS TeraStation TS-6VHL/E 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 TS-6VHL/E. 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.

How to recover data from a Buffalo

TeraStation TS-6VHL/E has 6 HDD slots, and it supports the following array types:

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

NAS supports:

  • 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 TS-6VHL/E 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 TS-6VHL/E device be done if the network interface is not functioning?
    • Hetman Software
      Hetman Software 29.08.2023 09:02 #

      Yes, data recovery from a NAS Buffalo TeraStation TS-6VHL/E device can still be possible even if the network interface is not functioning. The network interface is only used to access the NAS device over the network, but the data is stored on the internal hard drives.

      To recover the data, you would need to physically remove the hard drives from the NAS device and connect them to a computer directly. You can use a SATA-to-USB adapter or connect the drives internally to the computer. Once connected, you can use data recovery software or services to scan and recover the files from the drives.

      It's important to note that if the drives are part of a RAID array, the recovery process may be more complex, and it's recommended to seek professional assistance or consult the manufacturer's support for guidance.
