K-Probe...how do I interpret results?

[Mocha]

Just found out about this utility for detecting errors on cdrs using lite-on drives. Ran tests on 2 types of Fuji CDRs...one is Taiyo Yuden, the other is Prodisc Technology. Used the default settings, and am wondering what the results mean?


Prodisc Tech
Max Total Average
C1 14 2580 .652
C2 0 0 0

Taiyo Yuden
Max Total Average

C1 9 1978 .485
C2 0 0 0


What is C1 and C2? SHould I be concerned with the new Prodisc Technology made Fujifilm CDRs? Both play fine, but I wonder what the larger numbers for the Prodisc Fujifilm CDRs mean? Taiyo yuden makes cyanine and Prodisc uses phtalocyanine dyes.


Thanks

I recall seeing a bunch of threads covering k-probe over at doom9.

To me, your results look the same for both discs. I think C1 is a recoverable error, C2 is not. Can't really recall though. There was some debate about this.

I do know, that results varry widely depending on the drive. So comparisons with k-probe are inquestion unless they all come from the same drive. As your's did.

Go to the media forum at cdfreaks and you'll see a lot of information about scans with k-probe. They have quite a few tests on various disks in the stickied threads at the top of that forum.

Here is a link to the CD-Rinfo forum that has a Write quality document you can download. It explains C1/C2 errors. Basically, C1 are errors that can be corrected by the drive, C2 errors can be corrected but it depends on error length. The one parameter that Kprobe does not measure is C3(E32) errors. These are errors that cannot be corrected. This would be the Pop sound that you hear on a audio disk playback.

@Mocha,those scores are very good.
C1 errors are write errors and can be caused by:
1.Using outdated firmware
2.Poor quality media
3.Overburning
4.Using outdated burn software
5.Burning at high speed

C2 errors are usually caused by:
1.Physical damage-scratches,labels,ball point pens,etc.
2.Poor quality media

If I get less than these scores I'm happy:
C1 max-20
C1 avg-2.5%
C2 max/avg-0
...and of course DVD's use Tilt Analysis to test Parity Inner/Parity Outer(PI/PO).

tHANKS FOR THE REPLIES!!

I normally burn at the highest speed allowed by Nero...I first have Nero do a speed test....usually it burns between 32x and 48x....my max burn speed is 52x.
