Dear All,

It happened today that, after i burned a DVD from Nero, it shows no problem at all. However, when i try to read the DVD again, it shows that the disc are empty and cannot read the file.
I have tried many times, and still the same.

What is funny that, like 6 hours ago, when i burn the first one today, it WORKs. The DVD can be readable, but now, burning similar data files, it ends up that there do not show any problems in the burning log, and show that it has completed, just that windows shows it’s an empty disc.

I’m getting frustrated as i have no idea why it’s just SUDDENLY happened.
I tried reading another dvd again, but it’s still able to read.

Can anyone helps me ? Thanks.
