His original 250gb HDD was bad, I installed a new HDD WD Black 500gb and it was a few months of stress.
Games like Portal 2, Uncharted 3 and some others, installed on the HDD via PKG or ISO, had problems loading the scenery.
Uncharted 3 for example, in a part right at the beginning when we come out of a well - I forgot the name or chapter - the scenery didn't load, the ground didn't load, it was transparent. I reloaded the game several times and it had the same problem, until one day the map loaded, but the textures were in very low resolution, as if the system couldn't load and process them.
Interestingly, the HDD access indicator led at these times almost always had direct access, as if it were in a heavy transfer operation, and in some cases the led went off and didn't light up anymore, if I kept playing with the game it crashed and, if I tried to exit the game, the system crashed and restarted automatically.
Portal 2 had the same problem. (installed via PKG)
In a certain chapter, where we are escaping in a kind of tram attached to a rope, like a zip line - I haven't played Portal for more than half a year, please give me a break

- the 'tram' was crashing, with the textures in very low quality, the character would go forward but the tram would get stuck in the same place and then appear below his feet out of nowhere again.
Meanwhile the HD LED was on, but not continuously, it was on with a strong yellow color, like at maximum power, but it was blinking quickly because I could see the led oscillation between a maximum peak and a little below, actually reading files - trying - .
I also had problems loading scenery and texture in GTA 5 and TLOU, original Blu ray disc games.
In GTA 5 the scenery floor did not load, or the textures were like in the beta phase, very low, along with that the HD led was always on, at 'maximum power' but oscillating as it searched for files, until at some point the led went off and, if you continued playing, the system would lock and turn off only if you held the button for a few seconds; If the led was on intensely and suddenly went off, as before, and I tried to exit to the menu, the system also crashed and restarted.
already in TLOU the textures do not load on the faces of the characters but it did not crash the system; HD led on constantly.
These games that I had problems I tested both with the original HD and with the WD Black 500gb, and only with the WD did I get these problems, and when it was installed, the HD access led blinked much more than when with the original hd - in the same part of the scenery, or when loading the game.
