I/O errors

Ojla!

Imam manjši problem z peko DVD-jev. S pomočjo dvd shrinka si ustvarim iso datoteko, ki jo potem želim zapeči na dvd. Do tukaj deluje vse ok, napaka pa se pojavi, ko bi to računalnik dejansko moral izvesti. Datoteko sem probala zapeči že z dvd decryptorjem, nerotom in img burnerjem, vendar mi noben od teh ni naredil totalno ničestar. Vsak od teh treh programov mi javlja I/O error. Zanima me kako naj to napako odpravim, saj mi je do predkratkim vse delovalo.

Če bo v kakšno pomoč img burner mi v log-u napiše tole:

Običajne cd-je z glasbo mi bere in kopira uredu, dvd mi tudi lepo prebere in prekopira na disk.
