Asustor system failure

If you cannot access the data that was stored on your Asustor, then the possible reasons for the failure are the following:

  • Motherboard failure or power supply problem. In this case, typically, the device becomes completely inaccessible.
  • File system or volume manager failure. When this failure occurs, you may receive various error messages.
  • Failure of more disks than the redundancy allows. In this case, the entire array becomes inaccessible.

In the first two cases, there is a fairly high chance of recovering data stored on Asustor. But in the second case, if you cannot repair at least one of the broken disks, then, unfortunately, you will not be able to recover any data.

If you are faced with a system failure, then you definitely need to determine whether your Asustor is still under warranty. If so, be sure to contact the company's warranty department. They either identify the cause of the failure and fix it, or provide you with a new device. Unfortunately, it is not their responsibility to recover the data that was stored on disks from Asustor. Therefore, data recovery falls entirely on your shoulders.

A new Asustor NAS device or a repaired motherboard does not always recognize the original drives. Very often, a new device will simply begin to create the configuration again, which will undoubtedly lead to a complete loss of data stored on the disks. Therefore, for any type of failure in Asustor NAS device, the safest way is to recover the data, copy it to a safe place and only then find out what the problem is and how to solve it.

How to recover data in case of Asustor system failure

  1. Disconnect all hard drives from Asustor NAS, label them according to the bays and connect them to the computer. It is recommended to connect the drives directly to the computer's motherboard via SATA, because the recovery speed will be higher than with a USB connection, and the connection itself is much more stable. However, if your motherboard does not have enough free ports, you can connect using USB-to-SATA adapters with power.
  2. Download, install and run the ReclaiMe File Recovery software, which can recover data from Asustor devices.
  3. Select the volume from Asustor in the list of available devices in the ReclaiMe window and click Start. Typically, the volume from Asustor is located under the Linux md-raid volumes section. Asustor NAS recovery
  4. Wait until you receive a message that “Initial scan is completed”. After this, you can begin to analyze the recovered data - the size of the data, whether it is displayed correctly in the Preview. Pictures, PDFs, videos, mp3 files should look good. But some file types, such as exe, psd and others, are displayed in hexadecimal view.
  5. Prepare additional storage where you will copy the recovered data. Its volume should be equal to the volume of data, rather than the volume of the entire array.
  6. Buy an Ultimate license key and copy the recovered data to another storage device.

If you do not see the appropriate volumes in ReclaiMe File Recovery, most likely Linux driver metadata is significantly damaged. In this case, first you need to recover RAID configuration using ReclaiMe Free RAID Recovery. When the parameters are determined, select "Run ReclaiMe to recover data" in ReclaiMe Free RAID Recovery tool and back here.
