Synology Raid Recovery

Synology Raid Recovery

A Synology Raid Recovery or Network Attached Storage (NAS) can hamper, neglect, crash, fracture, or corrupt anytime as a result of physical, mechanical, and logical disk mistakes brought on by malware or virus disease, corrupted system files, abrupt power loss, damaged apparatus drivers, drive shutdown, improper storage or handling, bad sectors, etc.

While popular Synology RAID places like RAID 1, RAID 5, and RAID 6 may resist up to you to two disk failures, and those RAIDs can not withstand multiple disc corruption and loss as a result of logical errors and network crash.

When a RAID setup crashes or breaks, you’re generally left with just one alternative, i.e., RAID data recovery.

When we discuss Synology Raid Recovery, there are only a few choices, which can be as follow,

  1. Mdadm at Ubuntu
  2. Synology Data Recovery Technician for Windows

But before you move using Synology RAID data retrieval measures, here are some noteworthy pros and cons of every choice,

1.Mdadm for Ubuntu


  • Free


  • Complex for customers with no knowledge of Linux / consumers not familiar with the control line
      • Synology’s FAQ does not cover all Probable situations.
      • Requires a RAID hardware control

2. Synology Data Recovery Technician for Windows


  • Exceptionally intuitive and easy to use Windows RAID data recovery utility
      • A complimentary presentation version enables you to rebuild and scan busted or crashed Synology RAID for information retrieval.
      • Requires minimum attempts and perfect for novices in addition to professionals and power users
      • It doesn’t Take a hardware RAID controller.
      • Reconstructs ruined and crashed RAID even when parameters are either unknown or not supplied
      • Features photo and video repair modules along with also a Disk Monitor utility which helps in protected data recovery from broken up or crashed RAID 0, RAID 5, and RAID 6 arrays
      • Facilitates disk cloning comes useful if RAID drives are failing because of SMART or alternative logical mistakes.


  • A certified version of Synology Data Recovery Tech prices a couple of dollars to conserve the critical data in your free trailer window.

Now you know about most of the three potential choices to recoup information from a busted or crashed Synology RAID series, follow the actions given below to return your documents.

Steps to Recover Data from Broken or Crashed Synology NAS based on RAID 0, RAID 5, or RAID 6 Array

Since the Ubuntu manner is complex, we’ll detail the ® approach to recoup data from broken up or crashed Synology RAID. It is easier and secure as the computer program handles all of the complex jobs in the backend. Get the applications today!

Step 1: Disconnect RAID Drives

  • Eliminate all Drives in the busted or crashed Synology RAID place and join them into a functioning Windows PC through SATA connectors.
  • Instead, You Might utilize SATA to USB converter wires or timers to join Synology RAID drives to Windows PC or notebook.

Step 2: Inspect RAID Drives’ Health and SMART Status

  • Download, install, and then start the Synology Data recovery program and then click on the Waffle icon in the top right and then select ‘Monitor Drive.’

As an alternative, you might also utilize CrystalDiskInfo or a comparable SMART disk drive utility. However, Drive Monitor shows more detailed info regarding the disc health, functionality, and SMART status aside from clone disc choice.

  • Assess the complex drive wellbeing. If the utility exhibits a SMART warning or some other medical or performance-related warning signals, instantly replicate the disc.

Step 3: Clone Disk [Optional]

NOTE: This drive cloning is optional; however highly Suggested for secure data retrieval from neglecting RAID drives

  • Join a fresh or wholesome hard disk with a quantity size equal to or more prominent than the changed RAID drive
  • Click ‘Clone Disk‘ and then Pick the origin (changed drive) and goal disc (fresh or Healthful disk ) from various drop-downs
  • Click on ‘Clone‘ and click ‘start’ to take, and then begin the cloning Procedure.
  • Await the cloning procedure to complete. Repeat the following steps for additional degraded RAID drives

Following the disk, replace the degraded RAID driveway using a recently cloned hard disk and then move to another step to carry out simple data retrieval from linked RAID drives.

Step 4: Reconstruct Broken or Crashed Synology RAID Array

To rebuild a Synology RAID 0, RAID 5, or RAID 6 place, shut to the ‘drive Monitor’ utility (if operating ) and start the Synology Data recovery Tech tool.

  • Next, select what file types that you would like to recuperate and click on next.

Suggestion: You may add a habit or rare file format at the file listing for information retrieval. The ‘Insert Rename‘ option in Preferences permits you to add unlimited file formats also enables users to recuperate just about any file type.

  • Pick ‘RAID Retrieval‘ below Other Places and click on ‘Scan.’
  • Click the RAID tab RAID 0, RAID 5, or RAID 6. Each of the Synology RAID disks on the system is observable under select Hard pushes to rebuild the RAID’s record box.
  • Click onto a disc and use the arrow to remove or add RAID drives in your ‘select Hard pushes to Reconstruct RAID‘ listing box to ‘transfer hard drives up/down for disc arrangement‘ listing box. Repeat the following step to move all RAID discs.
  • Use the down and up arrow buttons alongside the list. See the box to organize drives in the ideal sequence since they were at the Synology RAID collection.
  • Input or choose all of the essential RAID parameter values and then click ‘Construct RAID.’

Suggestion: Pick they ‘do not understand…. .’ The alternative in case you don’t understand the critical RAID parameters. When parameters Aren’t supplied, the applications construct likely Digital RAID selection (s)

  • Wait until the computer program reconstructs that your RAID volume or likely RAID volumes.
  • Once RAID reconstruction, pick the RAID volume in the listing and click on the ‘scan’ button.
  • Following the scanning, when the wanted files aren’t seen in the scanning results, click on the ‘click Here‘ link at the bottom to start ‘deep‘ Scan.
  • Post quick or deep Scan; it is possible to click a document to view its preview or select the folders and files you would like to recuperate.
  • Click ‘Recover‘ then ‘Browse‘ to pick a save place –in which you would like to store the recovered information.
  • Last, click the ‘start Saving‘ button again. The chosen recovered folders and files will be stored in your preferred location.

Now you have access to your lost data from broken up or crashed Synology RAID, format every drive to build RAID out of scratch. And also, to steer explicit such data loss scenarios, keep at least two backup copies of your essential files.

Bear in mind, and RAID isn’t a backup or another alternate to copies!


Synology NAS, according to RAID, arrays could crash or break because of disk failure brought on by rational, mechanical, or physical mistakes. Frequently, it happens because of logical errors like file system errors, malware or virus disease, abrupt shutdown, and device driver problems, etc.

You can use mdadm controls to resync that the RAID array for data retrieval. However, mdadm operates in Ubuntu. In case you are not familiarized with Ubuntu or Linux command line, then leverage a potent RAID data recovery applications, for example, Synology Data Recovery Tech for Windows.

The latter process is far more straightforward and does not require any technical skills. If you’re familiar with Windows, then you may use Synology Data Recovery Tech to recoup information from a busted, shattered, degraded, or even corrupted RAID 0, RAID 5, and RAID 6 range.
