ReclaiMe Data Recovery Training

RAID Recovery Course - Overall Test

When to apply parity analysis?

before zero and mirror analysis
after zero and mirror analysis
after entropy analysis
between zero and mirror analysis

Is it possible to recover data if one of the member disks in a RAID5 failed?

depends on which disk failed
yes, all data is recoverable
yes, but only part of the data is recoverable
no

Look at the picture on the right and guess the possible RAID level

Full RAID 6 with a hotspare
Full RAID6
RAID 5 with a blank disk
RAID6 with a missing disk

What does content analysis help determine?

RAID level
disk order
block size

Look at the picture on the right and guess the possible RAID level

RAID 5 with a missing disk
RAID10
Full RAID 5 with a hotspare
Full RAID5

What information about RAID you can get just by looking at the disks in Disk Management?

block size
idea about first disk
idea about RAID level

What is the correct order of the content analysis stages in ReclaiMe Pro?

ratio of zeros, mirror analysis, parity analysis
mirror analysis, ratio of zeros, parity analysis
parity analysis, ratio of zeros, mirror analysis

If data recovered from a RAID is incorrect it means that

RAID configuration recovery failed
filesystem recovery failed
both filesystem or RAID recovery might fail, investigation is needed

Where is RAID metadata stored?

at the end of the member disk
at the beginning of the member disk
anywhere, depending on the implementation specifics

We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
