To budu chyby na disku.
Aj ked sa na to nikto nepytal, ale na kontrolu funkcnosti ATA diskov sa
da velmi dobre pouzit programcek z portov sysutils/smartmontools.
Pomocou SMART sa vie dotazat na rozne interne hodnoty disku (teplota
disku, kolko hodin disk bezal, kolko krat bol zapnuty, atd.). A okrem
toho, vie spustit test, ktory kontroluje stav disku.
Informacie o disku (v pripade ad0) sa zistia prikazom
smartctl -a ad0
Testy sa potom spustaju
smartctl -t short ad0
smartctl -t long ad0
(Vysledok testu sa opet zisti cez "smartctl -a ad0".)
Viac info samozrejme v manualovej stranke k smartctl.
