HDD - Need of Formatting ?

[Ironman]

I have faced a scenario where i have to erase all the data in a HDD and fill it again one one by while sorting the files properly
HDD in Question : Portable 1 TB Seagate
Main Reason to do it : Fragmentation

My Question.

Which one is better ? Quick Format or Full Format ? Which of them will enable less Fragmentation when i add files in the HDD
or both are same in that respect ?

From what I understand it is going to be the same. Difference will be for eventual effect on successful data recovery if such a case arises or to prevent it.
