And you don't, unless the CD mastering factory tell you. (or you use AccurateRip).
If you are talking about the internal error correction on the CD, you still don't get to know when it has failed. CDROMs are supposed to tell you about errors, but they often can't be trusted. andy b Wrote: > > Are you saying that if WMP10 says 'ripped to disk' with error > correcting on, it's lying, but if EAC says it ripped to disk, it's > telling the truth? > Yes. Especially with scratched CDs and old CDROMs. EAC gives different checksums than other programs (including itunes and realplayer). I believe that EAC is more accurate, because the AccurateRip plugin tells me that several other people have the same checksum. I think the ripping process is much more complicated than you think. It is not as simple as "read the bits several times". When you "read the bits", how do you know which bits they are? It isn't like a hard drive, where you simply say "read the 100th sector" -- clumsyoik _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
