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 the use of specific data recovery software or services impact the success rate of data retrieval from NAS QNAP TES-1885U(QES) devices?

Yes, the use of specific data recovery software or services can impact the success rate of data retrieval from NAS QNAP TES-1885U(QES) devices. The success rate depends on various factors such as the quality and effectiveness of the software or service, the nature and extent of data loss or damage, and the specific capabilities and compatibility of the software or service with the QNAP NAS device.

Using reliable and reputable data recovery software or services specifically designed for NAS devices can significantly increase the chances of successful data retrieval. These specialized tools often have advanced algorithms and features tailored for NAS systems, allowing them to effectively recover data from QNAP NAS devices.

It's important to note that the success rate of data recovery also depends on the state of the NAS device and the extent of data damage. If the NAS device is physically damaged or the data is severely corrupted, the success rate may be lower regardless of the software or service used.

To maximize the success rate, it is recommended to consult with professional data recovery services or use trusted data recovery software that has a proven track record with QNAP NAS devices.

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

Although NAS TES-1885U(QES) 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.

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:

Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
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.
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 QNAP TES-1885U(QES) network-attached storage keeps QTS (QuTS hero) 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.
