Questions about copying cds

Is drive read and write offsets something that's always there when I copy a cd or it's an issue only when I have to rip a cd with EAC? To be more precise, if I copy a cd (audio or data) with nero, the resulting cd will be different form the source cd because of drive offsets? And if so, is it possible to set read and write offsets in nero to have a perfect copy?

One more thing, I know my drive (Matshita UJ-840D) has a read offset of 102 samples, the write offset seems to be 0...and that's strage, but when I compare the CRC of 2 cd (1 used as source and the other ripped in EAC with the 102 read offset and burnt with EAC with 0 write offset or with Burrrn) I get the same value...is this enough to say my drive has a 0 write offset?

Make sure that the EAC option to use NULL samples in crc calculation is used otherwise different offset audio tracks will have the same crc.

Thanks for your advice, EAC had the option "no use NULL samples..." on so I turn it off and I compared the wav from the cd I burned with the one extracted from the cuesheet using foobar2000, and EAC tells me: "error: 30 repeated samples"... so I think the write offset is 30 (the same value of another guy with the same drive that was unsure) am I right?
