Chyby disku

Dobrý den,
v logu se mi objevily následující hlášky:

když jsem si dal vypsat informace pomocí smartctl, vypsalo se mi:

Znamená to, že ten disk je bez chyby nebo ne ? Když si výpis smartctl 
pustím na PC
s ATA disky (jiný počítač, jiné disky) vypíše to i počty tzv 
realocated_sectors, na tomto
PC ne, kde je chyba ?

Díky za každou radu
