Why is my shw-160p6s burning soo slow?

sup guys

i got a problem.

I’m hearing that people with 16x dvd burners are burning entire dvd’s in around 4-6 minutes but mine takes around 10-11mins.

1)udma is enabled (80pin). (my two hd’s are udma 5, my dvd-rom is multiwordDMA 2, and my shw-160p6s is set at udma 2.

  1. i get a 28mb/s burst rate

*3)when burning a dvd, the burner spins hard and then slows down repeatedly. buffer related?

what could the problem be? i’m thinking that maybe it’s because my burner is set a udma2. i tried and i can’t get it higher

thanks!

oh yeah, forgot to mention this…

when i start a burn in nero 7, i’m given an estimated time (say 5 mins). about 50 % into the burn in adds another 5 mins? this happens at 12x and 16x

…just tried two more burns and get this
8x takes 9mins
12x takes 9.5min
16x take 10-11mins

all while using sony dvd+r 16x media

Hi,

What media are you using? Run Nero CD/DVD speed and have a look at the “Disc Info” tab. Possibly your drive slows down as the discs you are using are not good enough to provide a 16x burn.

1)udma is enabled (80pin). (my two hd’s are udma 5, my dvd-rom is multiwordDMA 2, and my shw-160p6s is set at udma 2.
You are also using an 80 wired cable to connect your optical drives? Maybe it is your old DVD-ROM, that causes UDMA 4 not working. But UDMA 2 is still good enough to provide 16x speed with certified media.

Okay. These Sony D21 should do fine at 12x or 16x. The figures you posted, indicate slowdowns during the write process. These might be due to interface issues or a slow source drive. I think, we could exclude the media.

Please try this: Instead of burning your next DVD onto a disc, create an image file by selecting Nero Image recorder as writing device in Nero. Then run Nero CD/DVD speed again, select “Create Disc” and check the “Burn Image” mark. You can then burn your disc and record the write curve at the same time. Create a screenshot of the write curve (there is a tiny floppy icon) and post here, please.

what’s going on??

Okay.

Try this: disconnect your old DVD-ROM drive completely, set the jumper on your Liteon to Master and make sure, the drive is connected by an 80 wired IDE cable, also make sure, the cable is in good shape.
Then try again. Try also other media, Verbatims are good.
