Whats wrong?



I just installed a new motherboard (Asrock K7NF2-RAID with nForce2 Ultra 400) in my computer and did a complete new installation of WinXP SP3.
I do use a BenQ DW1655 BCIB. It used to run pretty good with the old mainboard. I allway got results like this one (burnt with 8x speed):

After changing the mainboard i got scans like this (settings where the same):
<a href=“http://picasaweb.google.de/HeikoJung85/DiscSpeed/photo#5213244531064155250”><img src=“http://lh4.ggpht.com/HeikoJung85/SFkqR7FTrHI/AAAAAAAAAEY/shwnkQ1RZU4/s144/MCC004%20-%20098th%20burn%20(%40%208x)%2C%20BCIB%2C%20Verbatim%20DVD%2BR%2016x%2C%20Graph.png” /></a>
What makes me wonder is first,that the scan with the new mainboard took way longer then with the old one. And second, the green line in the upper graph and the purple line in the lower graph was quiet straight. But now it’s going up and down all the time.
Does anybody have any clue what might be wrong? Do you need any further information?
Thx, Akantinuris

Edit: Otherwise, the DVD-scan burnt with the new mainboard looks a lil better, doesn’t it?



make sure, that Nvidia’s IDE drivers are not installed.



How can I do that? And is there any possibility to uninstall them? What are better IDE driver?


OK, I found out that I used the standart IDE-drivers. Just cuz i’ve been curios I made an image of my system and installed the latest nForce2-IDE drivers form the asrock homepage.
After that, I rescanned the DVD from the 2nd graph. This is the result:

More PI Erorrs and Failures, but a way better read curve and less jitter. So what drivers would you use?


So, last graph:

This is the same DVD as before, just scanned with my Samsung SH-S203D. Compared with the scan made with the BenQ (the one before), does that mean that the Samsung is the better reader? Cuz both PI’s are lower. Or is the BenQ DW1655 the more reliable scanner?


Samsung drives are probably the best readers of all the brands. that why there are less PIE and PIF.


And there’s the @1ECC vs. @8ECC thing for PIF reporting. :wink:
Benq: @8ECC
Samsung: @1ECC

In 8 ECC raws, of course you will most of the time find more errors than in a single one… :slight_smile:
