Is there a bug or problem with one of the audio dumping programs?

[pepsidrinker]

I dumped NFL GameDay 2001 again with -617 offset. Perfectrip and EAC both give different results. They both give silence at the end but there is more data at the beginning with Perfectrip. One of those programs don't seem to like high negative offsets.

I have uploaded the files if you want to see it in a hex editor.

http://rapidshare.com/files/96514065/Audio.rar.html

EDIT: These are without any gaps.

EDIT 2: I just checked 3Xtreme and the perfectrip dump has more data then the EAC dump. it's 32MB in size, I will still upload it if someone wants to take a look. It's combined offset is -617.

Could this just be my drive making these errors or the software itself. I am going to try something, I remember seeing an option in EAC to make the drive run up before extraction for drives that need that I am going to redump the track again and see if it matches the perfectrip track. EDIT: Made no difference.

[themabus]

is your drive offset 30?
it appears that EAC won't get audio from data-audio gap. it just adds padding zeroes. i think, maybe you should report this as a bug to EAC authors.
...
i just run into similar problem myself with an old PC game back from 91 and Alcohol 1.9.6.5429 can't extract it either. CloneCD can.

[pepsidrinker]

Yeah, my drive offset is 30. I will report this as a bug. Thanks for the advice. I wonder if perfectrip dumped all the audio date?

EDIT: Emailed him about it and gave the sample already uploaded.
