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.

If you do want a bit exact copy you will need 2 things:
1) A drive that can read into lead-in/-out (eg. older Plextor drives)
2) A drive that has got a write offset of 0 (eg. many LG drives - I use a newer LG BD drive for exanple)
As far as I know there has never existed a drive that could read into lead-in/-out and had a write offset of 0. So you will need two different drives. One for reading and one for writing. Although drives that can read into lead-in/-out nowadays are probably harder to find.

I do use an older Plextor drive with accurate rip software for reading and EAC for writing.
If I re-rip a copy, the copy is 100% bit identical to the original rip.
