Koristim MBP 2011 i nedavno sam stavio SDXC karticu na koju sam instalirao 10.12. Kada se stroj podigne radi normalno. Ipak često se zna desiti da se pojavi kernel panic. Primjetio sam da se uopće ne želi dignuti ako na primjer nije spojen na struju bez obzira koliki je postotak baterije. Isto tako SDXC kartica mi se ne pojavljuje na listi startup diskova. Za startanje sa kartice koristim alt tipku i onda odaberem SDXC.

Ispod je kopirana poruka koju dobijem nakon uspješnog startanja u crash reportu. Obzirom da mi ovo nije radni disk, jer imam SSD i HDD u svom MBP, nije mi od životne važnosti ali bih želio sa većom sigurnosti koristiti taj disk/karticu radi testiranja aplikacija koje su mi bitne jer sam još uvijek na 10.8.5

Svaka SD kartica otkazuje kad se pregrije. Ne da se pokvari, nego ima ugrađeni "thermal shutdown". Ovisno o čitaču koji je očitava ili zapisuje, visok protok podataka kroz predugo vrijeme bez prekida će je pregrijati pa će se ona sama od sebe "ugasiti" na sekundu-dvije, dok se ne ohladi. Tako da nikako nije baš neko pouzdano rješenje za koristiti je kao sistemski disk.
Ovo ti pišem na temelju iskustava s Raspberry Pi. On je dovoljno nezahtjevan da je takav koncept inače OK, ali se upravo iz ovog razloga povremeno zablokira kad ga ostaviš trajno uključenog da radi neki telematički posao (npr. da prikuplja neka mjerenja pa ih šalje ili poslužuje kao web server i sl. )

Hvala.
