Hi Kelvin, I did the test you talked about using the exact numbers you mention (they seem like as good as any to see if the pattern holds). The audio at those two points is *not* the same. In the RW_RAW file byte 24480000 is definitely the start of an audio sector because it follows what is obviously a subcode block. (lots of 0x00 and 0x40 values, the 0x40 bytes represent a set bit in the q channel). The audio that starts at 24480000 (0x1758900h) in the RW_RAW file is totally different to what ever the data is at 23520000 (0x166E300h) in the RW file. I also find it hard to believe that the drive buffers all the subcode and spews it out at the end of the track (although cdrdao might) so something else must be going on here. The end of the .bin file: The the end of the RW_RAW file there are lots of zeros (audio) interspersed with obvious subcode (0x08 representing p channel bit set and 0xC0 representing p and q channel set, this is what we would expect) The end of the RW file is full of zeros. As far as I can tell the last non zero data is at 641378399 (0x263AA85Fh). Both files are 642511872 bytes. The data near the end of the RW file does look very suspicious, it doesn't really look like audio to me but I could be very wrong there, and who is to say what audio looks like. :) I'll keep poking around.
