[pso] [tema3] scriere crc

[Bogdan Tenea]

Intampin urmatoarea difcultate: la scriere fac doua biouri pentru a citi
CRCul de pe hard, modific crcul sectoarelelor care se scriu pe hard, dar
dupa ce schimb directia bioului ca sa-l scriu incepe sa se blocheze cateva
secunde bune dupa da niste erori (nu da oops sau panic). Practic merge sa
fac submit bio, dar ramane blocat la evenimentul bioului respectiv. Am
incercat si sa clonez biourile inainte de scriere, sa folosesc bio_endio pe
cele initiale si sa folosesc alte 2 evenimente decat cele initiale, dar nici
un rezultat, mereu acceasi eroare.
