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 file system corruption impact data integrity on NAS Buffalo Drive Station HD-CE500LU2 devices?

File system corruption on NAS Buffalo Drive Station HD-CE500LU2 devices can have a significant impact on data integrity. Here are a few ways it can affect the device:

  1. Data Loss: File system corruption can result in the loss of data stored on the NAS drive. This can happen due to the inability to access or retrieve files, or even due to the complete corruption of the file system structure.
  2. Inaccessibility: Corruption can render the NAS drive inaccessible, making it impossible to access any files or folders stored on it. This can lead to a complete loss of data until the corruption is resolved.
  3. Data Corruption: The integrity of the data itself can be compromised during file system corruption. This means that even if the files are accessible, they may contain errors or be unreadable, resulting in data loss or incorrect information.
  4. Unreliable Backups: If the NAS drive is used for backup purposes, file system corruption can affect the reliability of the backups. Corrupted files or an inaccessible file system may prevent successful backups, leaving the data vulnerable to permanent loss.
  5. System Instability: File system corruption can cause the NAS device to become unstable, leading to frequent crashes, freezes, or other performance issues. This instability can further increase the risk of data loss or corruption.

To mitigate the impact of file system corruption on data integrity, it is important to regularly back up the data stored on the NAS drive to an alternative storage location. Additionally, implementing regular file system checks and maintenance, such as running disk checks and ensuring the device firmware is up to date, can help identify and resolve any file system issues before they lead to data loss or corruption.

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

Although NAS Drive Station HD-CE500LU2 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 Drive Station HD-CE500LU2 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.

      To recover data from a NAS Buffalo Drive Station HD-CE500LU2, you can follow these steps:

      1. Disconnect the NAS drive from the network and power source to prevent further data loss or damage.
      2. Remove the hard drive from the NAS enclosure. Refer to the user manual or online resources for specific instructions on how to do this for your particular model.
      3. Connect the hard drive to a computer using a SATA to USB adapter or by installing it directly into a desktop computer if possible.
      4. Once connected, check if the hard drive is recognized by the computer. Open "Disk Management" on Windows or "Disk Utility" on macOS to see if the drive is detected. If it is, you may be able to access the data directly. If not, proceed to the next step.
      5. Use data recovery software to scan the drive for recoverable files. There are several reliable options available, such as Recuva, EaseUS Data Recovery Wizard, or Disk Drill. Install the software and follow the instructions to scan the drive.
      6. After the scan is complete, the software should display a list of recoverable files. Preview the files to ensure they are intact and select the ones you want to recover.
      7. Choose a safe location to save the recovered files. It is recommended to save them to a different drive or external storage device to avoid overwriting any data on the original drive.
      8. Once the recovery process is complete, safely eject the hard drive from the computer and reconnect it to the NAS enclosure.

      Note: If the above steps do not work or if you are not comfortable performing the data recovery process yourself, it is advisable to seek professional help from a data recovery service. They have specialized tools and expertise to recover data from damaged or inaccessible drives.
