I think I did enough research before asking this question and I still didn’t find anything.
Both the short and long S.M.A.R.T. diagnostic tests run for around 5 seconds and then give me status codes 3… (In French: “Le S.M.A.R.T. de diagnostic terminé avec le code d’état: 3”).
I found a few posts from people asking about other status codes, but I found no list of all the status codes and their meanings anywhere…
What does status code 3 mean? What should I do to be able to complete the tests. I suspect there are bad sectors on the disk, but I can’t perform the S.M.A.R.T. test.
