How to recover lost files from Synology NAS DS415+

[David Simpson]

My Synology DS415+ NAS don’t turn on, it may be out of order.
There is no way to access the files by just connecting the disks to the computer. I can't try replacing the device itself - there is no similar device available.
How to extract data from hard disks after the NAS device broke down, from an inoperable disk array? (I hope that all drives are working and my data is still there)
Is there any well-tested data recovery tools for NAS solutions?

 

[Tech Junky]

Boot to a Linux USB

Install mdadm and scan to build the array and mount.

Disks should be fine and just need a new NAS or DAS to bring them online again.

And once you get your data recovered, I suggest reaching out to Synology Tech Support

The DS415+ has the Intel Rangely CPU, and there are known/documented issues with that CPU that result in devices suddenly not able to start up.

You might get a goodwill repair or a discount on a newer device...

Thank you. Useful article. I liked the idea with Windows+UFS Explorer.
I even googled a bit in this direction, and looked at the material similar to the one you recommended: https://hetmanrecovery.com/recovery_news/how-to-recover-data-from-raid-synology-nas-ds415.htm#plan_3
I understand that this is not the best solution, but people advise different programs. But, it looks so simple: connect the drives to the PC and it sees your array.
I want to get this experience, I will try. I will write about the result in time.

I tried the data recovery method described in this article, and everything worked out for me. The proposed program perfectly coped with its task.
Thanks to everyone who tried to help.

Great to hear! Did you reach out to Synology to see if they would replace/fix your unit?

I've reached out to Synology, but support answers with standard phrases and directs me to instructions from their knowledge center.
And I have no way to send it directly to Synology.
So, the device is sent to the nearest service center for repair.

Ah yes, the 'fake support' that is today's customer service. Have you tried contacting the nearest and see what they say?

No. Do you think this makes sense? I mean - contact the Synology service.

Can't hurt. It was a known issue.

And maybe consider a proper backup strategy for the future so you aren't scrambling trying to figure out how to recover data. Essentially, you got lucky this time. It may not be the same next time

Yep - NAS is never a backup - rather since it collects files from other sources, it absolutely needs to be backed up itself...

Synology and QNAP both include backup Apps for this purpose...
