Thanks for your answers:
I don't know witch type of write/reader they are so I'll put here what appears on the device administrator:
Hl-dt-st cd-rw gce-8483b
Hl-dt-st Dvd-rom gdr8162b
With those names, I can't recognize what model they are so if you, masters of the back-up can do that, I would be very pleased
Also i'll try copying a securom game too. Let's see what happens...
