Vypis meho disku vypada trochu jinak a treba u polozky 194 vidim
aktualni teplotu na 44°C. Worst je 57°C, coz je nejvyssi dosazena
teplota - to sedi. Ostatnim hodnotam moc nerozumim.
Jen doufam, ze tomu rozumi smartd a vi, kdy ma zareagovat. Mne by
zajimalo, jestli s tim ma nekdo zkusenosti a jestli to mam nastavene
spravne?
