I recently bought a Dell XPS 400 system. Rather than upgrading to the burner that they offered, I left it with a CD-RW and bought a Pioneer DVR-110D from Newegg. Set both drives up as master/slave on the primary IDE (HDDs are SATA), but BIOS does not recognize the burner (although Windows does)...not sure if this is part of the main problem or not. Anyhow, its an 8x burner but benchmarks at 1.3x. I finally checked the transfer mode and noticed that it is stuck in PIO mode, and Ive been unable to figure out how to change it. I attempted to uninstall the IDE channel and let it reinstall on reboot, but now BOTH drives are PIO only. I know Windows reverts to PIO after so many errors, but wouldnt these errors be brought to my attention? Ive had no known errors other than just very slow burns.
