EAC: Read/sync errors on brand new disc.

[Anthony J. Bertorelli]

I am having difficulty extracting two songs from a complilation I
purchased earlier. It will not extract tracks 11 and 12 without giving
me read/sync errors. At first I thought it was a bad disc, so I bought
a second one. When I bought an album by George Strait, I could not
extract the disc at all. It played fine on my CD player, but it would
not extract. I purchased a replacement, and it extracted without a
hitch. This, unfortunately, is not the case with the disc I am
currently working on. I am am having difficulty with the same two
tracks. Could someone explain why this is so.

I should point out that I can hear no audible errors, but I am sort of
a Nazi when it comes to exact audio copies.

Bad disk. Another disk drive might not think so, though. There aren't
necessarily absolutes about what is "bad". Some disks are better that
others, some hardware is better than other hardware; but it's it's all
relative. Factory disks generally have a higher error rate than disks I
burn myself, in my experience. Some factory disks *really suck*.

CD players can just breeze by errors and present you with "averaged"
data for spots where there are serious errors. Hardware CD players are
generally much better at that than the software CD players that you'll
find on your computer.
Capturing the analog audio from an external CD player might be the best
way to go if EAC ain't cutting it.

As I understand it, sync error means essentially that the drive could
not read the disc in that area well enough to make sense of the coded
data. You don't say whether your discs are pressed or burned, which
matters here; for that reason, the following largely assumes a burned disc.

Where you had success on the second copy, the cause of the first failure
was likely a spot of trouble on the original disc - a transient flaw, a
spec of dirt or something similar. Two copies failing in the same spot
almost certainly means a systematic failure which may be due to your
drive being misaligned relative to the one which wrote a burned disc, to
some anomaly in such burning - for example, a poor recovery from buffer
underrun forcing a resync when reading. Other possibilities apply for a
pressed disc.

You may be able to get insight into the problem by examining the
retrieved waveform in the neighborhood of the sync error. For example,
an array of short spurts of zeroes (~10-100 msec) near the end of the
disc generally indicates recording at too high a speed for the medium;
the same in a consistent region not at the beginning or the end suggests
buffer underrun protection is not properly protecting.

Thanks for the intel. I suppose I should have mentioned that it was a
pressed disc. Specifically, it was the Righteous Brothers compilation
entitled "Gold." Also, the read and sync errors occur regardless of
which drive I use. I don't hear any artifacts with the waveform in the
neighborhood of the read and sync errors, so I am just going to let it
slide. I do not want to buy a third copy and have the same problem
with extraction.

Guess Mikey couldn't figure that out from this:

Please note: I said to look at the waveform, not to listen to it. Error
concealment and properties of the ear make listening a poor way to find
such faults as these.
