Chyby cteni disku

[Kaminar]

Zdravim,

nedavno jsem kopiroval soubory z jednoho disku (byl sifrovany s geli).
Kopiroval jsem to MidnightCommanderem (konkretne MC z portu
misc/mc-light). Po dokopirovani jsem si vsiml hlasek na konzoli (viz
nize), ktere nasvedcujici tomu, ze je neco spatneho s diskem.

Chtel jsem se zeptat, jestli je nekdo schopen vycist z hlasek v logu,
jestli nektery sektor nebyl vubec precten a je tedy pravdepodobne, ze
data na kopii nebudou konzistentni, nebo se nakonec vsechno povedlo
precist byt s problemy? MC se totiz tvaril, ze kopirovani souboru
probehlo bez problemu a behem kopirovani nezahlasil zadnou varovnou
hlasku a ani se nechoval nijak podivne.
