Is this rip accurate?

[fartlekrun]

Hello all:

I ripped a CD a couple of months ago. With AccurateRip confidence of 1, result was:
3 track(s) accurately ripped
1 track(s) could not be verified as accurate
1 track(s) not present in the AccurateRip database

I ripped the disk a second time on a different computer with different drive. Same result.

Here's an excerpt from one of the EAC logs:

 1 track(s) not present in the AccurateRip database

Some tracks could not be verified as accurate

No errors occurred

Since the recent database update (thanks Spoon!), I ran an .accurip report which now says the rip is accurate with confidence 2. Here's the .accurip report:

Is this rip accurate?

This is a 23-year-old disk, so not common. I assume that the confidence 2 is the two rips I made of the same disk on two different computers, right?
Does that mean that I'm just seeing confirmation of possibly the same bad disk, or does this mean that it is indeed an accurate rip?

Thanks for any insight.

Re: Is this rip accurate?

You are comparing the same disc (from 2 different computers, which you own). The power of Accuraterip is to compare with someone elses disc, this rules out consistent errors.

Re: Is this rip accurate?

Right, I understand that. So does this mean that the database now has verification of two identical rips of a potentially bad disk?

Or, does the fact that I got the same result on two different computers mean that the disk is fine and the rip is accurate? Is it possible for two different drives to achieve identical rips yet both rips are inaccurate?

Re: Is this rip accurate?

It is difficult to say for certain, two different brands of CD/ DVD drive should be ok as long as they are not the same chipset internally (if they have different offsets they are ok).

Thanks.

Yes, the drives are different brands with different offsets.
