I will hack FILE_GetDeviceInfo just to make it recognize my cdrom as removable
and try to see if it helps.

However, I don't understand well why forcing the drive as cdrom (instead of relying
on autodetection) is not taken into account. This could be also usefull for ISO images.
Unless this option is planned to be removed !?!
