Ti suggerisco di NON acquistare il programma che hai citato (Registry Booster 2), giacché non sarà certo per quella via che riuscirai a sbrogliar la tua matassa...
L'hai fatto lo scandisk approfondito? Con quali risultati?

Per monsee, lo scandisk approfondito è andato OK
Per R16. provo alla pausa pranzo e ti faccio sapere
Ciao e grazie

OK tutto a posto, mi manca soltanto il SAMPLE
Ciao
