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 a UPS (Uninterruptible Power Supply) help minimize data loss risks during power outages or disruptions for NAS Buffalo LinkStation LS720D0802B devices?

Yes, the use of a UPS (Uninterruptible Power Supply) can help minimize data loss risks during power outages or disruptions for NAS Buffalo LinkStation LS720D0802B devices.

A UPS provides backup power to connected devices when the main power source fails. It acts as a buffer, allowing the devices to continue running for a limited period of time until power is restored or until the devices can be safely shut down.

In the case of a NAS (Network Attached Storage) device like the Buffalo LinkStation LS720D0802B, a UPS can help prevent data loss by providing enough power to keep the device operational during a power outage. This allows the NAS to properly shut down or go into a safe mode, preserving any data that is being written or accessed at the time of the power disruption.

Additionally, a UPS can also protect the NAS from power surges or voltage fluctuations that can occur during power restoration, which can potentially damage the device or corrupt the data stored on it.

It is important to note that the UPS should be appropriately sized to handle the power requirements of the NAS device and any other connected equipment. It is recommended to consult the manufacturer's specifications or seek professional advice to ensure compatibility and optimal performance.

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

Although NAS LinkStation LS720D0802B 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 LinkStation LS720D0802B 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.
