There is no need to preclear a drive before using it for Parity.  The preclear application writes zeros to the entire drive to prepare it for use as a data drive in the Unraid array.  As installing a new Parity drive requires the parity to be rebuilt which will write to every location on the drive anyway.


Here is the relevant section from the Unraid manual for replacing a Parity drive:

It's not needed, but if you want to test the drive to make sure it's trustworthy and not faulty, it is a good idea to run through preclear or smart long test or other extensive workouts.

so is it quite simple what to do after installing the app ?
