Hello again guys, I must ask another question again even though only few hours passed from my previous one.

I've did may simple test and none of them worked, I may know why it still not working but I need to hear from an expert.

Here's my problem:

Original CD Audio -> Rip to FLAC = Correct rip with AccurateRip. When I calculate the CRC/MD5 with dBpoweramp it gives me the same CRC for every lossless rip test I do with that very same track.

It seems though that I can't get the same CRC when I burn the track and re rip it. 1) Is my problem the absence of CUE files? 2) Does the track re rip correctly only if I burn it from the CUE file? 3) Is there a way to make a perfect burn without the CUE file? I've tried every possible burning software, burrrn, dBpoweramp, EAC etc.

Thank you again guys.

You should really stop relying on CRC. If even a single bit is different the CRCs will be completely different, so this is no indication of how different they are.

I haven't used EAC in several years myself, but someone here will tell you how to compare the two WAV files to find out exactly how they differ and whether or not it matters.
