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.

Can remote access to NAS Buffalo TeraStation TS5800D3208V5 devices pose additional data loss risks?

Remote access to NAS Buffalo TeraStation TS5800D3208V5 devices can potentially pose additional data loss risks if not properly secured and managed. Here are a few factors to consider:

1. Security vulnerabilities: If remote access is not properly secured, it can expose the device to potential security breaches. Hackers or unauthorized users may attempt to gain access to the device, potentially leading to data loss or unauthorized modifications.
2. Weak passwords: Weak or easily guessable passwords can make it easier for attackers to gain access to the NAS device remotely. It is important to use strong and unique passwords, enable two-factor authentication if available, and regularly update passwords to minimize the risk.
3. Network vulnerabilities: Remote access often relies on network connections, which can introduce additional risks. If the network is not properly secured, it may be susceptible to eavesdropping, man-in-the-middle attacks, or other network-based threats that can lead to data loss.
4. Accidental deletion or modification: Remote access allows users to access and manage the NAS device from anywhere, increasing the chances of accidental deletion or modification of critical data. Without proper precautions, accidental actions can result in permanent data loss.

To mitigate these risks, it is important to follow best practices for securing remote access to NAS devices:

• Ensure the NAS device's firmware is up to date to address any security vulnerabilities.
• Implement strong passwords and enable two-factor authentication if available.
• Use secure protocols such as HTTPS or VPN for remote access.
• Restrict remote access to trusted IP addresses or networks.
• Regularly backup data stored on the NAS device to an off-site location.
• Monitor access logs and enable alerts for any suspicious activities.
• Educate users about best practices and potential risks associated with remote access.

By following these precautions and maintaining good security practices, the risks associated with remote access to NAS Buffalo TeraStation TS5800D3208V5 devices can be minimized.

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

Although NAS TeraStation TS5800D3208V5 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.

   How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS5800D3208V5. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a Buffalo

TeraStation TS5800D3208V5 has 1 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 5;
• RAID 6;
• RAID 50;
• RAID 60;
• 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.

   

4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

   

Where are user’s files stored?

The Buffalo TeraStation TS5800D3208V5 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.
