so the thing is, i once swapped out my ps4 hdd from the official 500gb to a 2tb one. (Seagate one) the 2tb from the very first day made awful creaky and chirping sounds ,so it was unbearable. so i went on ahead and bought a 1tb by Toshiba (laptop sata 2.5") basically those that fit into the ps4. swapped it into it and has been splendid for the first 2 months, but now the 1tb is also making some weird very low pitched noise. and that noise can only be heard when i am playing a game or when i am downloading something, basically when i am putting the HDD to work i guess? it is abit annoying, but is this normal ? here is a link to what type of sound i mean with my current 1tb HDD. note: my ps4 is the newer model one , the all mat finish with physical buttons.
