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 recommended best practices for securely storing usernames and passwords on NAS Buffalo TeraStation TS-IX2.0TL/R5 devices?

Yes, there are several recommended best practices for securely storing usernames and passwords on NAS Buffalo TeraStation TS-IX2.0TL/R5 devices:

1. Change Default Credentials: It is essential to change the default username and password provided by the manufacturer. Use a strong, unique password that includes a combination of uppercase and lowercase letters, numbers, and special characters.
2. Enable Two-Factor Authentication (2FA): Enable 2FA if your device supports it. This adds an extra layer of security by requiring a second form of authentication, such as a code generated by a mobile app or sent via SMS.
3. Regularly Update Firmware: Keep your device's firmware up to date. Manufacturers often release security patches and updates to address vulnerabilities, so it's crucial to install them promptly.
4. Use Strong Passwords: Encourage users to choose strong, unique passwords for their accounts. Avoid using common passwords or easily guessable information like birthdates or names.
5. Limit Access: Grant access privileges only to necessary users and restrict access to sensitive data. Regularly review and revoke access for users who no longer require it.
6. Implement Network Segmentation: Separate your NAS device from the main network by using VLANs or separate physical networks. This reduces the risk of unauthorized access to the device.
7. Regularly Backup Data: Implement a regular backup strategy to ensure that your data is protected in case of hardware failure, accidental deletion, or ransomware attacks. Store backups in a separate location or on cloud storage.
8. Use Secure Protocols: Enable secure protocols like HTTPS or SFTP for remote access to the NAS device. This ensures that data transmission is encrypted and protected from eavesdropping.
9. Disable Unnecessary Services: Disable any unnecessary services or protocols that are not required for your specific use case. This reduces the attack surface and minimizes potential vulnerabilities.
10. Educate Users: Train users on good security practices, such as avoiding phishing emails, not sharing passwords, and being cautious when accessing the NAS device from public networks.

By following these best practices, you can enhance the security of your NAS Buffalo TeraStation TS-IX2.0TL/R5 devices and protect your usernames and passwords from unauthorized access.

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

Although the NAS TeraStation TS-IX2.0TL/R5 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 Order Remote Data Recovery

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS-IX2.0TL/R5. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

How to recover data from a Buffalo

TeraStation TS-IX2.0TL/R5 has 4 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 5;
• RAID 6;
• JBOD;

NAS supports:

• exFAT, VFAT, FAT 12 / 16 / 32;
• NTFS / ReFS;
• APFS / HFS+;
• Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
• VMFS / HikvisionFS;

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.

   

4. Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

   

Where Are the User’s Files Actually Stored?

The Buffalo TeraStation TS-IX2.0TL/R5 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.
