My nec is weird it burns everything at 4x speed maybe i got a bad batch of verbatims16x? But this also happens on TY02 media.
try create disc in nero cd dvd speed and see what you get
I know this is obvious but is the drive DMA enabled?
cnlson; The first pic is the burn
weedougie; yes of course
I always hear this high pitch noise when it starts to do @ 6x then when it goes back to 4x the noise disapears
Yet it looks it’s not… I can’t see any other reason than DMA disabled
Can we see a “burst rate” test from Nero CD-Speed?
From your graph it seems the drive is setup properly with UDMA mode enabled and a good “burst rate” test. I assume the hard drive is also UDMA enabled.
I think this leaves either a media problem, or some sort of drive failure. If possible try some other media, although if the media you have used is real TY and Verbatim, there shouldn’t be a problem with the media.
ive tried both + & - 16x verbatims and ty dunno if they are fake or not but doubt all 3 are fake i dunno… this made me order a benq 1650
