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 the use of deduplication or compression technologies impact data loss risks on NAS TerraMaster U16-420 devices?

The use of deduplication or compression technologies can potentially impact data loss risks on NAS TerraMaster U16-420 devices. Here's how:

Deduplication: Deduplication technology eliminates redundant data by storing only unique data blocks and creating references to them. While this can save storage space, it introduces a risk of data loss. If a single unique data block is corrupted or lost, it can affect multiple files or data sets that reference that block. Therefore, if deduplication is enabled on a TerraMaster U16-420 device, the risk of data loss increases as the integrity of each unique data block becomes crucial.
Compression: Compression technology reduces the size of files or data sets by encoding them in a more efficient format. While compression can save storage space, it also increases the risk of data loss. If the compressed data becomes corrupted or lost, it may not be possible to recover the original uncompressed data. Therefore, if compression is used on a TerraMaster U16-420 device, there is a higher risk of data loss compared to uncompressed data.

It's important to note that the impact of deduplication or compression technologies on data loss risks depends on various factors such as the implementation, reliability of the underlying storage system, and backup strategies in place. It's recommended to thoroughly evaluate the capabilities and limitations of these technologies and consider implementing proper backup and redundancy measures to mitigate data loss risks.

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

Although NAS U16-420 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.
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.
