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 Uniview 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 inadequate cooling or high ambient temperatures impact data loss risks for NAS Uniview DE3148-V2 devices?

Yes, inadequate cooling or high ambient temperatures can indeed impact data loss risks for NAS Uniview DE3148-V2 devices. NAS devices generate heat during operation, and if the cooling system is not sufficient or the ambient temperature is too high, it can lead to overheating of the device.

When a NAS device overheats, it can cause the hard drives to malfunction or fail, leading to potential data loss. High temperatures can also degrade the performance and lifespan of the hard drives, increasing the risk of data loss over time.

To mitigate these risks, it is important to ensure proper cooling for the NAS device. This can be achieved by placing the device in a well-ventilated area, using fans or cooling systems, and monitoring the temperature regularly. Additionally, it is recommended to follow the manufacturer's guidelines for operating temperature ranges and ensure that the NAS device is not exposed to extreme temperatures.

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

Although NAS DE3148-V2 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 Uniview DE3148-V2 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.

  To recover data from a NAS Uniview DE3148-V2, you can follow these steps:
  Check the hardware: Ensure that the NAS device is properly connected to the power source and the network. Make sure all cables are securely plugged in.
  Access the NAS interface: Open a web browser and enter the IP address of the NAS device in the address bar. This will take you to the NAS interface.
  Login to the NAS: Enter the username and password to access the NAS interface. If you don't have the login credentials, try using the default username and password provided by the manufacturer or contact the NAS support for assistance.
  Check the drive status: Once logged in, navigate to the storage or drive management section of the NAS interface. Check the status of the drives to ensure they are recognized and functioning properly. If any drive is marked as failed or offline, it may be the cause of data loss.
  Attempt data recovery: If the drives are recognized and functioning, but you are unable to access the data, you can try using data recovery software. There are several options available online, such as EaseUS Data Recovery Wizard, Recuva, or Disk Drill. Download and install the software on a computer connected to the same network as the NAS device. Follow the instructions provided by the software to scan and recover the lost data.
  Seek professional help: If the data recovery software fails to retrieve your data, it is recommended to contact a professional data recovery service. They have specialized tools and expertise to recover data from NAS devices. Be prepared for potentially high costs associated with professional data recovery services.
  Note: It is always recommended to have a backup of your important data to avoid data loss situations. Regularly backing up your data to an external storage device or cloud storage can help prevent the need for data recovery in the first place.
