If you bought a new HDD, it might have a filesystem already. Why not use
that one as is? You can create a new filesystem too [0] of course but
that will "delete" all existing data on the disk -- you can not damage
it physically though it that is your concern; you just write new
metadata (the new filesystem) onto the disk that is all.

From my point of view, if you have a filesystem you can use right away,
do so -- why spend time for something, when afterwards nothing really
changed from a users point of view.

If however the HDD does not have a filesystem installed already and/or
you want to have a secure i.e. encrypted disk [1], then you need to
install a new filesystem. If you decide to have an encrypted disk, you
might also want to initialize the disk for better security[2].
