Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Buffalo often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Are there any specific system logs or event notifications to monitor for early detection of data loss on NAS Buffalo TeraStation TS5400R1604 devices?

Yes, there are specific system logs and event notifications that you can monitor for early detection of data loss on NAS Buffalo TeraStation TS5400R1604 devices. Here are a few key logs and notifications to monitor:

  1. System Logs: The system logs on the TeraStation device can provide valuable information about any errors or issues that may indicate data loss. These logs can be accessed through the device's web interface or management software.
  2. RAID Status Notifications: The TeraStation device supports RAID configurations for data redundancy and protection. Monitoring RAID status notifications can help you identify any issues with the RAID array, such as failed drives or degraded performance, which could potentially lead to data loss.
  3. Disk Health Monitoring: Monitoring the health and status of individual hard drives in the TeraStation device can help you detect any potential drive failures or errors that might result in data loss. The device usually provides disk health monitoring features that can alert you to any problems.
  4. SMART Monitoring: Self-Monitoring, Analysis, and Reporting Technology (SMART) is a feature supported by most hard drives. Enabling SMART monitoring on the TeraStation device can provide early warnings about potential drive failures or issues that could lead to data loss.
  5. Email Notifications: The TeraStation device allows you to configure email notifications for various events, including disk errors, RAID failures, and system errors. Setting up email notifications can help you receive immediate alerts about potential data loss situations.

It's important to regularly review these logs and notifications to ensure early detection of any data loss issues and take appropriate actions to mitigate them.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS TeraStation TS5400R1604 can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually Stored?

The Buffalo TeraStation TS5400R1604 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.
