Zdravím,

mám 320GB disk Hitachi a nevím, zda ho mám reklamovat.

Pomocí příkazu

smartctl -t long /dev/hda

jsem si vytáhl SMART informace o disku. Výsledkem bylo, že harddisk prošel testem, viz

SMART overall-health self-assessment test result: PASSED.

Chápu, co určují hodnoty Reallocated_Event_Count, Current_Pending_Sector a Offline_Uncorrectable. Nevím, co udává hodnota UDMA_CRC_Error_Count a jaká je její závažnost.

Dále mi není jasné, co znamenají chyby (celkem 9), které se zapsaly do logu (viz dolní část výpisu), přitom disk prošel testem.

V manpage smartctl jsem našel význam zkratek, které jsou ve výpise uvedeny, ale úplně nechápu jejich význam a vliv na funkčnost harddisku.

ABRT:  Command ABoRTed
ICRC:  Interface Cyclic Redundancy Code (CRC) error

Bude harddisk fungovat dál v pořádku nebo je to důvod k reklamaci? Díky za odpovědi.
