samsung DVD burner SH-S128SF

[avextraxjp]

I'm got a samsung DVD burner SH-S128SF which takes about 1 hour 10 minutes to burn a 4.7GB DVD+R at 8X speed.

I've exhanged the drive for a replacement but the same problem persists after burning about 4-7 DVDs. I have tried DVDs of different brands with same results. Apparently, CDs burned at 36X also take longer than normal to complete. I run Windows XP SP2 and I have checked that DMA is enabled. I've sent the drive for a replacement again, Samsung could not provide an explanation and the technician detected nothing wrong about my computer.

My PC is a Pentium 4 3 GHz with 512 MB RAM.
What could be the problem?
Thanks.

what burning software program are you using? use IMGBURN to burn dvd media. also what brand of dvd media are you using? crappy media like MEMOREX which is manufactured by RITEK is not good to use.

your computer details say you're using VISTA as your operating system. but your post says you're using XP which is it? it sounds like your drive could be dying and most manufacturers will give you a replacement drive that is a refurbished one.

Sounds like the IDE channel has defaulted to PIO mode.

this particular computer is using XP.
I'm using Nero to burn DVDs at that time.
The DVDs I used range from Verbatim, HP DVD (CMC). No diffrence on the burning speed.
Is there an explanation?

You say you have dma enabled, but it sounds like pio mode to me. And it happens after your replacement burned a 'few disks'. Not an unusual problem with some windows computers.

This may not be the problem but dude, get some ram. OK back to the problem. If windows thinks its having a problem with a drive it goes to PIO mode and stays there. And sometimes its hell on earth to get it back to dma. You may have dma set but its in pio anyway.

What causes this? Bad ribbon cables for one. Install a new one. Using the correct ribbon cable for for highest speed IDE. Then you have to get that baby back into DMA mode. Do a search for this particular problem. Usually killing off the IDE in your computer equipment screen and then letting it autodetect and reinstall the IDE will do the trick.

The symptoms say PIO. But there is one other device that can be PIO, and that's your hard drive. This usually happens when the computer experiences something like a power failure or multiple power drops. So check the IDE channel for your hard drive as well. If this was the case you'd probably have slow booting and stuff so this is a low percentage issue.

Its probably the damn ribbon cable.
