"There are no folders on drive", the EMU E64 tells me.
I'm thinking it might have to do with the kind of Raw Mode / non-Raw Mode and buffer length in Nero.
It has worked before but I do not remember the exact settings.

Btw, I'm burning to CD-RW and it has been erased before every burn session.
Does anyone know the exact settings in Nero for burning EMU images, or what else could be wrong?
