Lite On 40125s not burning in disk at once

My 4 months Lite On 40125s is not burning in disk at once anymore, i have tested it with different nero versions & and under XP & win98, same results …

in Disc at one, burner hang just after beginning to write after the first 5% red led on, can’t explain why.

cds burned very well in Track at once instead of DAO

i tried with latest firmware and with overclocked 48125w firmware too : same pb

Who can help me ? :confused:

Post the complete record of a recent burn failure in DAO mode from the NeroHistory.log in the Nero directory and maybe we can spot a clue for the cause of this malfunction.
