How to recover HDD on new NAS???

[Vince C]

Hi,

I had a Zyxel NAS 320 with two WD 1TB harddrives (one as RAID). The NAS stopped working (actually it wouldn't turn off!), and Zyxel customer support said it was a hardware failure issue, and I would need to purchase a new NAS. So, I picked up a Zyxel NAS 325, expecting that it would be easier to read the HDD with the same NAS brand. I was wrong!!

The NAS 325 can't see the volumes on the HDD's, and wants to create a new volume, which would wipe out my data.

How do I access the data from the NAS 320 using with a new NAS??? Please help... we have a lot of family info on it.

thanks,
Vince

I would contact Zyxel's customer support folks first regarding the volume migration post-HW failure of the older NAS.

Consider it a lesson learned - NAS's need to be part of the overall backup plan, just like other devices..

Worst-case scenario (if they don't support disk migration) is to plug it to a computer running Linux (or using a Linux LiveCD) to recover the content. There's a good chance the disk is formatted in a Linux filesystem.

The challenge here is that his disks are configured as a RAID - so depending on how Zyxel handles this (most do thru mdadm, which is good perhaps), and how the volumes were handled - lvm or not? and then the filesystem on top of things - which depends on a fair amount of knowledge and skill with the deep dark insides of Linux disk management...

It is possible - there's a writeup over on anandtech that walks thru a HW failure and data recovery on Synology... which is a good first step as to investigate the challenges above I mention...
