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 TerraMaster 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 TerraMaster F8-421 devices pose additional data loss risks?

Remote access to NAS TerraMaster F8-421 devices can potentially pose additional data loss risks if not properly secured. Here are some factors to consider:

Security vulnerabilities: Enabling remote access exposes the NAS device to potential security vulnerabilities. If the device is not adequately protected with strong passwords, firewall settings, and regular security updates, it may become an easy target for hackers.
Unauthorized access: Remote access increases the chances of unauthorized users gaining access to your NAS device. If someone gains unauthorized access, they may be able to delete, modify, or steal your data, leading to potential data loss.
Network vulnerabilities: Remote access relies on network connectivity, which introduces additional risks. If the network is not properly secured, it may be susceptible to attacks like man-in-the-middle attacks, where an attacker intercepts the communication between the remote device and the NAS device, potentially leading to data loss.
Human error: Remote access increases the likelihood of human errors that can result in data loss. For example, accidental deletion or misconfiguration of settings while accessing the NAS remotely can lead to irreversible data loss.

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

Use strong passwords and enable two-factor authentication.
Regularly update the NAS firmware and security patches.
Configure firewall settings to restrict access to trusted IP addresses.
Enable encryption for remote connections using protocols like SSL or VPN.
Regularly backup your data to an off-site location to minimize the impact of data loss.

By implementing these security measures, you can reduce the potential risks associated with remote access to NAS TerraMaster F8-421 devices and protect your data from loss.

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

Although NAS F8-421 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:

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.
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.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
