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.

Are there any recommended steps to take after detecting or suspecting data loss on a NAS Buffalo DriveStation DDR device?

If you suspect or detect data loss on a NAS Buffalo DriveStation DDR device, here are some recommended steps to take:

  1. Stop using the DriveStation: As soon as you suspect data loss, stop using the device to prevent further damage or overwriting of the lost data. Continuing to use the DriveStation may reduce the chances of successful data recovery.
  2. Check connections and power supply: Ensure that all cables are properly connected and the power supply is functioning correctly. Sometimes, data loss can occur due to loose connections or power issues.
  3. Restart the DriveStation: Try restarting the device to see if it resolves any temporary issues causing data loss. Sometimes, a simple reboot can fix minor glitches.
  4. Contact Buffalo support: Reach out to Buffalo support for assistance. They may provide specific troubleshooting steps or recommend professional data recovery services.
  5. Data recovery software: If the data loss is due to logical issues rather than physical damage, you can try using data recovery software. Install a reputable data recovery tool on a separate computer and connect the DriveStation as an external drive to scan and recover lost files. However, be cautious as improper use of such software can further damage the data.
  6. Professional data recovery services: If the data loss is severe, involves physical damage, or you are unable to recover the data using software, it's best to seek professional data recovery services. These experts have specialized tools and expertise to recover data from damaged or corrupted devices.

Remember, data recovery success rates vary depending on the extent of damage and the actions taken after data loss. It's crucial to act quickly, avoid further damage, and consider professional help if needed.

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

Although NAS DriveStation DDR 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.

DriveStation DDR has 1 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • 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 Tools – Save 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 DriveStation DDR 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.

Questions and answers

  • What are the benefits of adding an additional hard drive to a NAS Buffalo DriveStation DDR?

    Adding an additional hard drive to a NAS Buffalo DriveStation DDR can provide several benefits, including:

    1. Increased storage capacity: The additional hard drive allows you to expand the overall storage capacity of your NAS device. This is particularly useful if you are running out of space on your existing hard drive and need to store more data.
    2. Data redundancy and protection: By configuring the additional hard drive as a RAID (Redundant Array of Independent Disks) array, you can achieve data redundancy. This means that if one hard drive fails, your data will still be accessible and protected on the other drive(s). This helps to prevent data loss in case of a hardware failure.
    3. Improved performance: With multiple hard drives, you can configure the NAS in RAID 0 mode, which combines the storage capacity of all drives and improves read and write speeds. This can result in faster data transfer rates and improved overall performance.
    4. Flexibility and scalability: Adding an additional hard drive allows for future expansion and scalability. As your storage needs grow, you can easily add more hard drives to the NAS device, providing a flexible and scalable storage solution.
    5. Simplified backup and data management: With multiple hard drives, you can set up automatic backups and implement data management strategies such as mirroring or data striping. This simplifies the backup process and ensures that your data is protected and easily accessible.
    6. Load balancing and improved network performance: By distributing data across multiple hard drives, you can balance the load and reduce the strain on a single drive. This can help to improve network performance and prevent bottlenecks when multiple users are accessing the NAS simultaneously.

    Overall, adding an additional hard drive to a NAS Buffalo DriveStation DDR enhances storage capacity, data protection, performance, and flexibility, making it a valuable upgrade for users with growing storage needs.
