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 TS3210DN0802 devices?

Yes, there are several recommended best practices for securely storing usernames and passwords on NAS Buffalo TeraStation TS3210DN0802 devices:

1. Change default credentials: Immediately change the default username and password provided by the manufacturer. Use strong, unique passwords that are not easily guessable.
2. Use complex passwords: Use a combination of uppercase and lowercase letters, numbers, and special characters in your passwords. Avoid using common or easily guessable passwords.
3. Enable two-factor authentication (2FA): Enable 2FA whenever possible. This adds an extra layer of security by requiring a second form of authentication, such as a code sent to your mobile device, in addition to the username and password.
4. Regularly update firmware: Keep the firmware of your NAS device up to date. Manufacturers often release firmware updates that include security patches and bug fixes.
5. Disable unnecessary services: Disable any unnecessary services or features that are not being used. This reduces the attack surface and minimizes the risk of unauthorized access.
6. Limit access privileges: Grant access privileges only to the users or groups that require them. Restrict access to sensitive data and ensure that users have the least amount of privileges necessary to perform their tasks.
7. Implement strong network security measures: Secure your network infrastructure by using firewalls, intrusion detection systems, and virtual private networks (VPNs). This helps protect against unauthorized access and data breaches.
8. Regularly backup your 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 securely, preferably off-site or in the cloud.
9. Educate users on security best practices: Train your users on security best practices, such as creating strong passwords, avoiding phishing emails, and not sharing their credentials with anyone. Regularly remind them to follow these practices.
10. Regularly monitor and audit access logs: Monitor access logs for any suspicious activities or unauthorized access attempts. Regularly review and audit these logs to identify any potential security issues.

By following these best practices, you can enhance the security of your usernames and passwords stored on NAS Buffalo TeraStation TS3210DN0802 devices and reduce the risk of unauthorized access or data breaches.

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

Although the NAS TeraStation TS3210DN0802 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 TS3210DN0802. 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 TS3210DN0802 has 2 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;

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 TS3210DN0802 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.
