I have recently purchased a Plextor 40 12 40 Rewriter but have been having problems with burning. I have install Nero 5.5.7.3 that came with the drive but when I try burning at 24X (The speed of the CDs I've got) it runs both buffers down alot and takes around 9 mins to burn a CD. This is burning directly from a 7,200 HDD not another CDROM Drive, although the problem does arise from CDROM too. I have the CDROM and Plextor on the same IDE cable at present. When Nero completes it states that there were around 160 Buffer Unnder-runs avoided. What can I do to get the most out of my Burner? Any help appreciated!
