My process includes running CUETools.ARCue.exe against each rip I do; if the analysis comes back with sample differences and no accurate rips at the CTDBID level, that extraction is filed separately for repair.
A recent rip of this disc got flagged as needing repair due to this block in the log:
[ CTDBID ] Status
[694191f3] (275/285) Differs in 3414 samples @36:25:74-36:26:04
[873d51b7] (006/285) Has pregap length 00:00:00, Differs in 3425 samples @36:25:74-36:26:04

[be3f4c65] (001/285) Has pregap length 00:00:00, No match
Fair enough. But! The log also contains this output in the per-track analysis:
Track | CTDB Status
1 | (285/285) Accurately ripped
2 | (285/285) Accurately ripped
3 | (285/285) Accurately ripped
4 | (284/285) Accurately ripped
5 | (285/285) Accurately ripped
6 | (285/285) Accurately ripped
7 | (283/285) Accurately ripped
8 | (285/285) Accurately ripped
9 | (285/285) Accurately ripped
10 | (281/285) Accurately ripped
The AccurateRip analysis in the same log indicates consistently that T10 is bad.
A second rip on a different drive comes back as fully accurate across the board, in the per-CTDBID results, the per-track CTDB results (with T10 at 284/285 -- no idea where the "284" comes from, see the full log below) and the AccurateRip results.
Bit-comparing the first and second rips in foobar2000 shows differences in 5342 values (fb2k counts differences in the L and R channels at a given sample position separately) but by my count there are actually 3543 sample positions with differences between the bad rip and the good one so I'm not sure what the "differs in samples" value is actually counting. (Not saying that's directly relevant, just calling it out.)
Worse: CUETools doesn't see the first rip as needing repair even though it doesn't match the fully-verified second rip. A Verify run in CUETools shows the first (bad) rip as accurately ripped at the track level and a fix-and-encode run on the bad rip results in a bit-identical output file, which CUETools.ARCue.exe still reports the same sample differences in. If not for my using the --verbose option in CUETools.ARCue.exe, which forces output of the per-CTDBID results, the initial bad rip would pass as accurate.
Complete log files follow. Results are identical in v2.2.2, v2.2.0 and v2.1.8. Any thoughts on what's going on here would be appreciated.
