 I got sata DVDRW drive.  I will add  test results .
 
 Motherboard is Supermicro H8DCE-HTE  
   based on NVIDIA nForce Pro/2200/2050 chipset
   (so have NVIDIA nForce4 IDE and Serial ATA Controller).
 
 ide  DVDRW drive is PIONEER DVD-RW  DVR-111
 sata DVDRW drive is ASUS DRW-24D5MT
 
 With these drive write  NetBSD-8.99.8-amd64.iso  to dvdrw media with 
 
 dvdrecord -dao -v blank=all  dev=/dev/cd0d
 ( or dvdrecord -dao -v blank=fast  dev=/dev/cd0d )
 dvdrecord -dao -v  NetBSD-8.99.8-amd64.iso  dev=/dev/cd0d
