I only recently tried burning at 16x with my new NEC, and noticed it has problems reaching that speed. First of all, some background info: Windows 2003 SP1 here, burned using CD Speed 4.01. Drive is secondary master, with LiteOn 832S being secondary slave and data source being primary master. Device manager lists both NEC and LiteOn as UDMA-2. I tried copying back the source ISO and it was stable 32mb/s. Interface burst speed for nec was reported as 24mb/s. Firmware being 1.W3.
Now, all the 3 discs I tried (Verbatim 16x DVD-R, Verbatim 16x DVD+R and Fuji 8x (Yuden T002)), turn out looking like the attached pic.
What could be the problem here? Is my drive fuxored?
