Asustor Recovery

Asustor NAS device is a fairly popular solution for storing large amounts of data. In Asustor NASes, hard drives are combined into a single storage using the RAID technology. As for the file system, Asustor NASes are typically formatted with EXT filesystem.

If the RAID configuration is lost or some kind of file system failure occurs, or the NAS box fails, then from the user’s side it may look like this:

  • In the NAS control panel, you see that the RAID status is shown as Failed and you cannot access data.
  • Your Asustor NAS just doesn't turn on.

In both cases, there is still a chance to recover data. You should use a special software which is capable of recovering data from NAS devices like ReclaiMe File Recovery software.

If your Asustor NAS is working properly and all you need is to recover accidentally deleted data, try ReclaiMe NAS Recovery first: it can recover data from NAS devices directly, you do not need to get the disks out and the like. Refer here for the detailed instructions on how to recover deleted files from a Asustor drive.

Asustor NAS recovery with ReclaiMe

  1. Remove all the disks from the Asustor box, label them according to the bays where there were inserted. Labeling is not useful for the recovery process, because the software can automatically determine the disk order. However, labeling may help if something goes wrong.
  2. Connect the disks from the Asustor to the PC running Windows. We recommend connect the drives directly to the PC motherboard using SATA ports on the motherboard. However, if your motherboard does not have enough free SATA ports you can use USB-to-SATA adapters.
  3. Download and launch ReclaiMe File Recovery software.
  4. Select your Asustor NAS volume in the software window. Most likely, the volume is located under the Linux md-raid volumes section. Asustor volume for recovery
  5. Wait till the software starts bringing data. Note that ReclaiMe is designed to bring data earlier into the scan and you do not need to wait till the end of the scan. Typically, you get all the files within 3-5%.
  6. Estimate the recovery result using the Preview function. If image files (.jpg, .tiff) or .pdf files are displayed well, most likely, the rest of the files will be opened correctly after saving.
  7. Purchase the Ultimate license key.
  8. Copy the recovered data to storage device prepared in advance. This can be an external drive (s) or another NAS.

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.
