Re: Discs won't EAC secure, 2nd best option?

Secure rip. Turned off C2 and 'drive caches audio data.' Left 'Accurate Stream' on.

Probably as good as it's going to get unless I ask for a reburn (don't really want to bother the guy) or try a different drive?

Would you seed this on a band specific tracker where 95% of the downloaders could care less and the other 5% will download it just to have a copy of the show? ...I know kind of a silly question.

Read mode : Secure with NO C2, accurate stream, NO disable cache
Combined read/write offset correction : 0
Overread into Lead-In and Lead-Out : No

Used output format : Internal WAV Routines
44.100 Hz; 16 Bit; Stereo

Other options :
Fill up missing offset samples with silence : Yes
Delete leading and trailing silent blocks : Yes

Track 1
Filename C:\Documents and Settings\john\Desktop\Track01.wav

Peak level 100.0 %
Track quality 99.9 %
Test CRC 40B41EC0
Copy CRC 2C7271F6
Copy OK

No errors occured
End of status report

Re: Discs won't EAC secure, 2nd best option?

No luck with test & copy + speed-limited burst rip?

Personally I'd usually try to extract it on different drives or ask for a reburn as a last resort, but I dunno whether I'd do the latter for an LP2 show (unless it's a show I really care a lot about)

Re: Discs won't EAC secure, 2nd best option?

It says "Copy OK" so you have a secure rip that you should not be ashamed of.

my only suggestion is to calculate & set your read offsets (not that it matters for a 1-track disc.

*ehem* note the crc mismatch, though.

oh thanks I see the problem now

is there a way to pinpoint the exact problem spot? this track will at least need to be listened to very carefully with headphones!

edit: also perhaps try burst mode to see if you can get that same crc as ssamadhi suggested

also, is it possible that it is the test crc which is incorrect? EAC reported no errors ripping secure but got a different crc which seems strange that it would still say "copy ok" I would think this copy is perfect. somebody told me that "copy ok" is golden.

Re: Discs won't EAC secure, 2nd best option?

Well, here are the possible scenarios:
1) copy crc correct, test crc incorrect
2) copy crc incorrect, test crc correct
3) copy crc incorrect, test crc incorrect

I guess with problematic discs, 3) is the most likely. And I doubt that 1) is any more likely than 2).

Keep in mind that EAC has no way to actually verify that a track was extracted correctly. Roughly, it bases its "copy ok" tag on the assumption that if it reads a sector n times and gets the same result (let's say x) m times, the cd actually contains x (and not y). However if during the test pass it mostly reads x, and during the copy pass it mostly reads y, there's no way to know whether the cd actually contains x or y. It's even possible that the data originally stored on the cd was z. (all iirc)

...hope that made sense


Edit: note that matching crcs in burst mode don't necessarily indicate a perfect rip either, especially not on problematic discs. iirc people have been reporting (audibly) "better" results with burst mode though.

but no error checking? I would like to get my hands on a burst rip that sounds better than a secure rip of the same material and zone in on exactly what the differences are. the trouble with burst is that if there's a pop/click there is no error report made. which means that even if burst is better, it requires manual error checking which is even more difficult than it sounds.
