ReclaiMe Data Recovery Training

NAS Partitions - Practice part

Before recovering data from a NAS, data recovery technicians should think what partition layout they may expect on NAS disks. You can get a lot of information from a client's description. Data recovery software capable of parsing NAS metadata can give you even better picture.

Task 1 - Determining a partition layout

Assume that a client brought you a NAS with 6 bays – 1 2 3 4 5 6, and told that first only two 500 GB disks were in the NAS (in the 1st and 2nd bays). Some time later two more 1 TB disks were inserted to the 3rd and 4th bays and then 2 TB disks were inserted into all bays. The client said that disk replacements were performed one by one and after each replacement the array was synchronized.

You need to answer the following questions:

  1. How many and what md arrays are there on the NAS disks after all these upgrades?
  2. Whether the final layout depends on the order of 2 TB disk replacements – from left to right (from the 1st bay towards 6th) or from right to left?

Task 2 – Determining a partition layout working with a set of screenshots of NAS disks

Based on a ReclaiMe Pro screenshot, you are offered to draw a partition layout on NAS disks. This disk set came from a 4-bay NetGear NV+ v2 NAS. What interesting things you see?
