I'm using and Optorite DD0405 and a NEC ND-1100A to burn on my computer. Now the DD0405 is both + & -, plus it is 8x. The NEC is 4x and+, so I try to use the DD0405 more often.

The only problem with that drive is there is a high chance (30%?) that midway through the last track it will make an error of some type and the track will lock up at that point. And when I flip the disc over and look at it, I can see a huge gap of blank space towards the end of the disc. This happens regardless of media brand (I've tried Memorex, Sony, TDK, and some generics). I'm using 160E firmware.
