Summary: A degraded, broken, or crashed Synology RAID is a critical situation that can lead to permanent data loss. But with prompt action, you may rebuild or reconstruct a corrupt RAID and get access to your data. In this guide, you will learn how to fix and recover lost data from a broken or crashed Synology RAID NAS safely with Stellar Data Recovery Technician software.
A Synology RAID set or Network Attached Storage (NAS) may degrade, fail, crash, break or corrupt anytime due to mechanical, physical and logical disk errors caused by virus or malware infection, corrupt system files, sudden power loss, damaged device drivers, force shutdown, improper handling or storage, bad sectors, etc.
While popular Synology RAID sets such as RAID 1, RAID 5, and RAID 6 can withstand up to one to two disk failures, these RAIDs can’t withstand multiple disk failure and corruption due to logical errors and system crash.
When a RAID set breaks or crashes, you are generally left with only one option and, i.e., RAID data recovery.
When we talk about Synology RAID recovery, there are only a few options, which are as follow,
But before you proceed with Synology RAID data recovery steps, here are some notable pros and cons of each option,

Now that you know about all three possible options to recover data from a broken or crashed Synology RAID set, follow the steps given below to get back your lost files.

Since Ubuntu way is complicated, we will detail the Stellar® way to recover data from broken or crashed Synology RAID. It’s much easier and safe as the software handles all the complicated tasks in the back-end. Get the software now!
Alternatively, you may also use CrystalDiskInfo or similar SMART disk utility. But Drive Monitor displays more detailed information about the disk health, performance and SMART status besides an option to clone disk.
Disk cloning is important as any further rigorous data recovery scan and actions can cause drive failure, leading to permanent data loss.
NOTE: This drive cloning is optional but highly recommended for safe data recovery from failing RAID drives
After the clone, replace the degraded RAID drive with a newly cloned hard drive and proceed to the next step to perform effortless data recovery from connected RAID drives.
To reconstruct a Synology RAID 0, RAID 5, or RAID 6 set, close the ‘Drive Monitor’ utility (if running) and launch the Stellar Data recovery Technician tool.
TIP: You can add a custom or uncommon file format in the supported file list for data recovery. The ‘Add Header’ option in Settings allows you to add unlimited file formats and enables users to recover virtually any file type.
TIP: Choose the ‘Don’t know…..’ option if you don’t know the required RAID parameters. When parameters are not provided, the software intelligently constructs probable virtual RAID array(s)
NOTE: Never choose the affected RAID drive(s) (source drive). Use an external USB drive or internal disk volume with enough storage space to save recovered data. In case your system is running low on storage, save the scan information to recover data in stages.
Now that you have access to your lost data from broken or crashed Synology RAID, format each drive to construct RAID from scratch. And to avoid such data loss situations, always keep atleast two backup copies of all your important files.
Remember, RAID is not a backup or an alternative to backups!
Synology NAS based on RAID arrays may break or crash due to disk failure caused by logical, mechanical, or physical errors. Often, it occurs due to logical errors such as file system errors, virus or malware infection, abrupt shutdown, device driver issues, etc.
You can use mdadm commands to resync the RAID array for data recovery. But mdadm works in Ubuntu. If you aren’t familiar with Ubuntu or Linux command line, leverage a powerful RAID data recovery software such as Stellar® Data Recovery Technician for Windows.
The latter method is much easier and doesn’t require any specialized skills. If you are familiar with Windows, you can use Stellar® Data Recovery Technician to recover data from a broken, crashed, degraded, or corrupt RAID 0, RAID 5, and RAID 6 array.

Can we do this using the Mac version of Stellar Data Recovery Technician? or is this capability is only available on the Windows version? Thanks in advance.
*totally in panic. My Synology drive crashed with no other backups. help!
Can you elaborate on Step 1? If I have 5 sata 8tb drives configured in a shr2 raid format what equipment cables controllers etc would I need to connect all of that to my windows machine?
You don’t need any controller but may need a PCIe SATA Expansion card to connect multiple drives via SATA Cable. You may also use SATA to USB Converter but check if your system has 5 USB 3.0 slots. USB 2.0 also work but the process will be much slower.
Once connected, open the Disk Management tool to check if all drives are shown. Then use the software to rebuild a virtual RAID by following the steps and recover your data. After recovery, you can rebuild RAID from scratch and then move your recovered data to new RAID array.
