QNAP VS-12140U-RP Pro+ NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VS-12140U-RP Pro+.

How to recover data from NAS QNAP VS-12140U-RP Pro+

Recover data from damaged RAID arrays inaccessible from a computer.

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 QNAP 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 excessive drive spin-down or power-saving settings impact data retrieval in case of failure on NAS QNAP VS-12140U-RP Pro+ devices?

Excessive drive spin-down or power-saving settings can potentially impact data retrieval in case of failure on NAS QNAP VS-12140U-RP Pro+ devices.

When drives are set to spin down frequently or power-saving settings are enabled, they may take longer to respond when accessed. In the event of a failure or error, this delay can further complicate the data retrieval process.

Additionally, if the drives are set to spin down too frequently, it can increase wear and tear on the drives as they constantly start and stop, potentially leading to premature drive failure.

It is recommended to strike a balance between power-saving settings and data accessibility, ensuring that the drives do not spin down excessively and are readily available when needed. Regular backups and monitoring the health of the drives can also help mitigate the risks associated with power-saving settings.

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

Although NAS VS-12140U-RP Pro+ 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.
