Let me be the first to say that my understanding of CD burning is far from deep.
Here's my problem: My Lite-On LTR-32123S drive has recently begun refusing to burn at a speed above 8-12x. This started in the middle of a spindle of CDs (rated at 16x). I get a 'Could not perform EndTrack' error at the end of the burn, which is undocumented on the nero website, as well as the occasional buffer underrun
Additionally, all the test burn options are greyed out in Nero now. I should add that this is fro burning data CDs from the hard disc, nothing fancy.
I have tried the following:
-Reinstalled Nero (OEM) and patched to 22.214.171.124
-Updated drive firmware to XS0Z
-Disabled the drive's DMA in windows and BIOS (per Nero website advice). This has resulted in the warning message "recording Quality may be affected by not using the JustSpeed option." when burning (successfully) at 8x
OS: Win2k SP3, fairly lean set of services running
Dual Athlon MP 2100 on Tyan Tiger MPX motherboard (BIOS 4.03d)
Burner is Master on an IDE cable shared with a DVD-ROM drive, which has been inactive during failed burns.
Any help you can give, or advice as to how to approach troubleshooting the error would be very welcome.
