NAS Recovery Preparations - Practice part

Task – Detection of suspicious disks based on the S.M.A.R.T. data

Before starting to recover data from NAS disks, data recovery technicians should do the following:

• Ask a client about a NAS (model, vendor, and so on) and about NAS failure (what has failed, what is the cause of failure, and who tried to do what after the failure).
• Check the state of NAS disks based on the S.M.A.R.T. data.

In the task, you are offered to work with the S.M.A.R.T. data screenshots coming from different disks. Note that disks are not from one array. Based on the screenshots, you need to determine what disks are healthy, what are bad and, therefore, have to be cloned.
