How to recover data from NAS QNAP SS-EC1279U-SAS-RP

QNAP SS-EC1279U-SAS-RP NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from SS-EC1279U-SAS-RP.

How to recover data from NAS QNAP SS-EC1279U-SAS-RP

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.

How can network issues impact the data stored on NAS QNAP SS-EC1279U-SAS-RP devices?

Network issues can impact the data stored on NAS QNAP SS-EC1279U-SAS-RP devices in several ways:

  1. Slow data transfer: Network issues such as high latency, packet loss, or network congestion can result in slow data transfer speeds. This can affect the performance of the NAS device and cause delays in accessing or transferring data.
  2. Data corruption: Network issues can lead to data corruption during file transfers. If packets are lost or corrupted during transmission, it can result in incomplete or corrupted files on the NAS device.
  3. Inaccessibility: Network issues can cause intermittent connectivity problems, making the NAS device inaccessible from other devices on the network. This can prevent users from accessing or retrieving their data stored on the NAS.
  4. Data loss: In severe cases, network issues such as power outages or network hardware failures can result in data loss on the NAS device. If the network connection is abruptly interrupted during a write operation, it can result in data loss or file system corruption.
  5. Backup failures: Network issues can also impact the backup process for the NAS device. If the network connection is unreliable or experiences frequent interruptions, scheduled backups may fail, leading to potential data loss if no other backup mechanisms are in place.

To mitigate the impact of network issues on NAS devices, it is recommended to:

  • Ensure a stable and reliable network infrastructure with proper cabling, switches, and routers.
  • Monitor network performance regularly to identify and address any network issues promptly.
  • Implement redundancy and backup strategies to protect data in case of network failures.
  • Regularly update firmware and software on the NAS device to ensure compatibility and security.
  • Consider implementing RAID configurations or other data redundancy mechanisms to protect against data loss.
  • Utilize UPS (uninterruptible power supply) systems to protect the NAS device from sudden power outages.

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

Although NAS SS-EC1279U-SAS-RP 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.

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:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. 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.

Where are user’s files stored?

The QNAP SS-EC1279U-SAS-RP 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.
