All

I've been handed 2x 1TB inernal drives by a client that allegedly came from a Synology NAS device - I believe DS 210+ .

Viewing these drives they both contains 3 partitions, one EXT3 (2GB), One Unknown (2GB) and the remainder ~990GB in another unknown format partition.

I'm being told these two form a RAID volume - but havent had any luck figuring out how to recreate the raid virtually without the enclosure. Anyone familiar with these NAS devices and if there is a way I can access the data without the original NAS device?

Thanks
Matt

The default on Sinology is SHR or SHR2 , check their site for some details.
There is however a complete step by step mounting for recovery report here

It was sometime ago now, using EnCase 5 or 6 I was able to acquire both drives separately then configure them as a RAID within EnCase.

Sorry, don't remember the detail and not sure if other Forensic Tools do the same job as [thankfully] not had one since!! 😯

I presume you can't see the data, Matt. We had a Synology NAS box with two 1TB drives the other day and one was simply a mirror of the other.

You need to know if the NAS was RAID-1 or RAID-0 If the capacity was approx. 1TB, then it is RAID-1, if it was approx. 2 TB, then it was RAID-0.

RAID-1, ignore the word RAID, both disks should be the same.
RAID-0, you will need to work out the stripe size and disk order
I have seen RAIDs where they start RAID-1 (for system partitions) and then go to RAID-0

By you indication of 990GB free space it looks like RAID-1.

Common file systems for RAIDs include XFS, Reiser 3fs, and Ext4

Quoting myself roll

The default on Sinology is SHR or SHR2 , check their site for some details.

https://www.synology.com/en-us/knowledgebase/tutorials/492

Is SHR required?

No, it is not necessary to use the SHR. The SHR is based on a Linux RAID management system, and is completely optional to use. However SHR is strongly recommended for the novice user who has no technical background and still want the benefit of data protection on their storage. Using Classic RAID-levels is available for those users and administrators who understand the finer points of RAID technology and want to manage the RAID volume manually. The following manual RAID levels are available

  1. JBOD
  2. RAID 0
  3. RAID 1
  4. RAID 5
  5. RAID 5+spare
  6. RAID 6
  7. RAID 10
