My 451S@CG3B Doesn't read/write CD

I insert CD, drive spins up,down,up,down and ejects CD (every CD).
It also doesn’t read DVD+RW.
Recording works fine (DVD+R/-R).
Maybe somebody had similar problem? Please help!

That’s odd. My 451S with CG3B reads CDs and +RWs fine. Have you tried flashing back to VS0B or a 451S or 851S firmware to see if it still does the same thing? You can use the firmware on my site to do this.
