DVD Burning Problem

[antoniomch]

Hi all
I hope some one of you can help me
I'm having problems burning DVD's. During the burning process I have no errors, but after that, when

the files are verified against the original ones, I have errors. The files are different...
I have two DVD burners. The same happens with both.

DVD burners I have: LG GSA-4081B and a Samsung TS-H552B
The Software I tested: Nero and Roxio and WriteMAster from Pinnacle
I have only one burning software installed at a time

What have I done with no results:
Updated my motherboard bios
Formatted my PC and installed Windows XP SP2 and made all the updates
Upgraded the firmware of the drives
Used the latest drivers to XP
Tested different brands of blank DVD's
Tested all kinds of DVD's (+/-R and RAM in the LG)
Tested different burning software
Tested in low burning speeds
Changed the transfer mode from DMA to "PIO Only" of the DVD drives
Tested the LG GSA-4081B in another PC
And I bought a gun to shoot my PC (kidding)

I think that it's very unlikely to be a DVD burner defect, because the same thing happens with both DVD

burners, and the same thing happened in the other PC with the LG GSA-4081B

I'm in a dead end.... HELP!!!

Thanks
António

1. try other media.

2. how are you verifying the burn? do you use the option in Nero to verify the data burned? well, the data verification of Nero is notorious for being inaccurate.
if these are data DVDs use some other means of verifying if the files are identical or not.
www.elpros.si/CDCheck for example.

Thanks and yes, I will try another media. I've already tested 3 different brands, but all of the were cheap ones.

About the verification process I've done it in two ways
I used the Nero verification option, and i used the 'FC' command ander DOS command prompt.
Same result for both

[dodecahedron]

i recommend CDCheck, but if you used fc then the files are probably indeed different.

what is it exactly that you are burning ?

I wouldn't worry about it,verification is a waste of time and I never use it.
I use KProbe or CDSpeed to check the disc for errors.

[dodecahedron]

well, if a disc has excellent burn quality but the wrong data burned onto it, it's trash.

I'm burning files, I wanted to use the DVD writer to backup my files

[dodecahedron]

well, in this case it is important to verify your burned data.
and like i said, i don't trust Nero's verification (i've heard too many instances where it didn't work well).
i use CDCheck.
