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.

How can software bugs or glitches impact data integrity on NAS Buffalo Drive Station HD-HS1.5TQ devices?

Software bugs or glitches on NAS Buffalo Drive Station HD-HS1.5TQ devices can impact data integrity in several ways:

  1. Data corruption: Bugs or glitches in the software can cause data corruption, where the stored data becomes unreadable or unusable. This can result in the loss of important files or documents.
  2. File system errors: Software issues can lead to file system errors on the NAS device. This can cause the device to be unable to properly organize and manage the stored data, leading to data loss or inconsistency.
  3. Data loss: In extreme cases, software bugs or glitches can cause data loss on the NAS device. This can happen if the bug affects the device's ability to properly write or save data, leading to permanent loss of important files.
  4. Incomplete or failed backups: NAS devices often have built-in backup functionality. However, software bugs can interfere with the backup process, resulting in incomplete or failed backups. This can leave the user without a reliable backup of their data, making recovery difficult in case of data loss.
  5. Performance degradation: Bugs or glitches in the software can also impact the performance of the NAS device. Slower data transfer speeds, unresponsive interfaces, or frequent system crashes can all affect the overall integrity of the stored data.

To mitigate the impact of software bugs or glitches on data integrity, it is important to regularly update the device's firmware to the latest version provided by Buffalo. Additionally, maintaining regular backups of important data on separate storage devices or in the cloud can help minimize the risk of permanent data loss.

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

Although NAS Drive Station HD-HS1.5TQ 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.

Questions and answers

  • What is DLNA and how does it work?

    DLNA stands for Digital Living Network Alliance. It is a set of guidelines and standards that enable devices to share media content over a home network. DLNA allows devices such as smartphones, tablets, computers, game consoles, and smart TVs to connect and communicate with each other seamlessly.

    DLNA works by establishing a local network, typically using Wi-Fi, Ethernet, or Powerline networking. Devices that are DLNA certified can discover and communicate with each other on this network. This allows users to stream or share media content, such as photos, videos, and music, from one device to another.

    The DLNA protocol ensures interoperability between different devices by defining a common set of rules and formats for media streaming. It uses standard networking protocols like UPnP (Universal Plug and Play) and HTTP (Hypertext Transfer Protocol) to facilitate device discovery, media browsing, and content streaming.

    When a DLNA-certified device is connected to a network, it broadcasts its capabilities and services to other devices on the network. These devices can then discover and access the media content available on the DLNA device. For example, a DLNA-certified smartphone can browse and play music stored on a DLNA-certified computer or stream videos from a DLNA-certified media server to a smart TV.

    DLNA also supports various media formats and codecs, allowing devices to transcode media on the fly if necessary. This ensures that media content can be played on different devices, regardless of their supported formats or codecs.

    Overall, DLNA simplifies the process of sharing and streaming media content within a home network, creating a seamless multimedia experience across multiple devices.

  • How does the NAS Buffalo Drive Station HD-HS1.5TQ utilize DLNA protocol?

    The NAS Buffalo DriveStation HD-HS1.5TQ does not directly utilize the DLNA (Digital Living Network Alliance) protocol. The DriveStation is a network-attached storage (NAS) device that provides centralized storage and file sharing capabilities within a local network.

    However, the DLNA protocol can be used in conjunction with the DriveStation to stream media content stored on the NAS to DLNA-certified devices such as smart TVs, gaming consoles, or media players. To enable DLNA streaming, you would need to set up a DLNA server software on a computer or a compatible NAS device connected to the DriveStation. This server software scans the DriveStation for media files, indexes them, and makes them available for streaming over the network using the DLNA protocol.

    Once the DLNA server is set up, DLNA-certified devices connected to the same network can discover and access the media files stored on the DriveStation through their respective media player applications. This allows you to stream videos, music, and photos directly from the DriveStation to your DLNA-enabled devices without the need for additional cables or file transfers.
