A Synology NAS is a shared disk storage device that allows you to centralize and backup data from multiple computers and mobile devices. This ensures that your data is more available, more reliable, offline-accessible, and searchable. It may also serve as a file server to handle various business purposes such as e-mail and websites. A Synology RAID storage also provides the fault tolerance features that may protect your valuable data in case of unexpected hard disk failure or other hardware failure.

But Sometimes, Synology RAID sets or Network Attached Storage (NAS) may fail and lose data due to mechanical, physical and logical disk errors caused by virus or malware infection, corrupt system files, sudden power loss, damaged device drivers, and forced shutdown .

And the best way to attempt Synology RAID data recovery is by contacting a specialist data recovery company in Melbourne and Sydney such as Recovery Squad. Recovery Squad  have the knowledge and expertise to get your Synology NAS servers back up and running, and we employ the latest technology in order to ensure complete Synology RAID recovery.

Here, we explains;

MOST Common Reasons of Synology Raid Drive Failure. 

In this case, a human being made the mistake that caused your RAID array to be lost.

This is the most common reason to fail the Synology NAS array. We find lots of incidents where humans make mistakes and the result is data loss. Sometimes a human is changing an array, but accidentally entered the number of drives incorrectly or didn’t know that they need to stop the RAID rebuild process before adding a new drive

Hard Drives Failure 

You can get into trouble when you’re running a RAID-5 storage configuration and you inadvertently put two hard drives into service with only one of them being available for use. Or, If the unit was exposed to a power surge or fire. In these cases, it is usually possible to recover data from at least one or two disks.

If an error occurs during RAID rebuild

In some situations, a hard disk has failed. This drive is replaced. However, the device begins a rebuild process. If this process is interrupted by a power loss or if a second disk fails during that process, it can leave the array confused.

Data loss can occur if you’re not careful during a firmware update, or if your drive’s firmware fails.

Every firmware update puts your data at risk, but it’s still a good idea to do it from a digital security perspective that might let you take advantage of any new features of DiskStation Manager or new RAID configurations. While this is a rare condition, it does happen. If an administrator is patching the firmware, for example, this would be good practice from an IT security perspective.

The Synology NAS was unable to start, but the RAID volume is fine. 

In general, problems with NAS devices are rare, and the devices are more reliable than hard drives. However, If you have a Synology DiskStation NAS (Network Attached Storage) and it breaks down, we’re able to help recover the data from any drive in case there is a problem with the chassis model. We can also replace faulty drives, upgrade your memory and CPU, and connect USB devices like printers and scanner.

But before you proceed with Synology RAID data recovery, There are many reasons why you might not want to use RAID recovery with Ubuntu. Here are just a few of them:

Mdadm in Ubuntu

  1. Not everyone is comfortable with the command line, and the installation process can be confusing even for users who are comfortable with Linux.
  2. Since your specific use case may be slightly different from most people using Synology products, you may want to consult Synology’s community forums for more specific information.
  3. You will need a hardware controller for your software RAID.
