Thanks for the reply, my laptop from the factory comes in a variety of versions. Mine is the one with the i5 4200H, Full HD screen and 500GB HDD and 128gb SSD. The 500Gb was probably taken out (Possibly from the shop I bought it, I don't have a clue) and replaced with an old 320Gb one which has at least 2 or 3 years of use if I am not mistaken according to HD Sentinel. The SSD is still inside the laptop (I will have to remove the full case to have access) connected on a M.2 port, it's only recognized in BIOS.
checked that he didnt put a dusty piece of shit in your laptop
The current Seagate 320gb HDD has 1128 days of use and 8300 start/stop count, quite old + slow HDD, I will look into replacing it with another one sooner or later, not having the funds at the moment.
