OT: on the Fly cd-cd

I'm out of ideas, I posted this in alt.comp.hardware.. Maybe some
overclockers could help me :)

Hi

I'm having a problem with on the fly copying.. I get this message

This device doesn't support the commands need ofr this (" Read Buffer" and
"write Buffer")

I have swaped the drive from my 12xdvd to my Acer 48X. I still get this
message.

thing. I also had no problems before with this untill I formated and
started from strach.

Abit VH6 (via chipset)
