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 specific system logs or event notifications to monitor for early detection of data loss on NAS Buffalo TeraStation TS3220DN0402 devices?

Yes, there are specific system logs and event notifications that you can monitor for early detection of data loss on NAS Buffalo TeraStation TS3220DN0402 devices. Here are a few examples:

  1. RAID Array Status: Monitor the RAID array status logs to ensure that all drives in the array are functioning properly. Any errors or warnings related to the RAID array could indicate potential data loss.
  2. Disk SMART Status: Keep an eye on the SMART (Self-Monitoring, Analysis, and Reporting Technology) status of each disk in the NAS. SMART provides information about the health and reliability of the drives. If any disk shows signs of failure or imminent failure, it's crucial to address it promptly to prevent data loss.
  3. File System Errors: Monitor the system logs for any file system errors. File system errors can indicate corruption or other issues that may lead to data loss.
  4. Backup Status: Check the backup status logs to ensure that regular backups are being performed successfully. If backups fail or encounter errors, it could indicate potential data loss if the primary data becomes corrupted or lost.
  5. Network Connectivity: Monitor the network connectivity logs to ensure uninterrupted access to the NAS. Network connectivity issues can prevent data from being accessed or written to the NAS, potentially resulting in data loss.
  6. User Access and Permissions: Keep track of user access logs and permissions to detect any unauthorized access or changes to files and folders. Unauthorized access could lead to data loss or compromise.

By regularly monitoring these logs and event notifications, you can detect potential issues early on and take appropriate actions to prevent data loss on your Buffalo TeraStation TS3220DN0402 devices.

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

Although NAS TeraStation TS3220DN0402 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.

TeraStation TS3220DN0402 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;

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 TS3220DN0402 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.

      Yes, there are specific techniques used in data recovery from NAS Buffalo TeraStation TS3220DN0402 devices with RAID configurations. Here are some common techniques:

      1. Rebuilding RAID Array: If one or more drives in the RAID array fail, the first step is to replace the faulty drives with new ones. Once the drives are replaced, the RAID array needs to be rebuilt using the appropriate RAID management software provided by Buffalo.
      2. Data Reconstruction: In case of data loss, data reconstruction techniques are used to recover the lost data. This involves analyzing the remaining drives in the RAID array and reconstructing the missing or corrupted data using parity information or other redundancy mechanisms.
      3. Data Carving: Data carving is a technique used to recover individual files or folders from a NAS device. It involves scanning the NAS storage for specific file signatures or patterns and extracting the fragmented or deleted files.
      4. Logical Recovery: Logical recovery techniques involve repairing the file system and recovering the data by repairing or rebuilding the logical structures of the NAS device. This can be done using specialized software tools that can analyze and repair the file system.
      5. Physical Recovery: In some cases, if the NAS device or the drives have physical damage, physical recovery techniques may be required. This involves repairing or replacing the damaged hardware components to access the data.

      It is important to note that data recovery from RAID configurations can be complex and should be performed by experienced professionals. It is recommended to contact a professional data recovery service provider for assistance with NAS Buffalo TeraStation TS3220DN0402 data recovery.
