a) If you plan to encrypt the drive, VeraCrypt “full format” when encrypting will fill the whole HDD with random data. If there’s a bad sector or corruption, VeraCrypt will let you know or you can use CrystalClearlnfo application simultaneously.
b) If you’re not planing to encrypt it, do the “complete format” option on Computer.
c) Any application that overwrite with one and zero (just search for them) and then use CrystalClearlnfo.
Each one of these options can take a long time to finish, a 5TB HDD can take 12 hour in each of these options.
