Here's all the details..

I'm disappointed that Sanyo didn't make this tool available for free. $91 is a little pricey as it is.

Interesting info here. I know many of you have been wondering what "good" PI results look like. Here they are according to Sanyo:

Please refer to the following reference value and comments as a guideline for judgment of the written status of media based on the measurement data.。 　

PI：Below 50 - There is no problem for data error detective amount. There is no data error occurred on the output data.
　
PI：50 and over - There is a slight problem for data error detective amount. There is no data error occurred on the output data
　
PI：250 and over - There is a problem for data error detective amount. Although data error doesn’t occur when UncorrectablePI is not detected, data error may occur when UncorrectablePI is detected.

I forgot about the demo!

Then those are the numbers for the average, or for Max? Either way, my burns are right way down there.

I'd guess it means that any spike over 50 means a detectable error and a spike over 250 might signify a serious error, provided it is an uncorrectible PI.

Ian, you should get them to donate a copy for CDRLabs - it sounds like it'd make a good test tool...

Yes, $91 definitely seems pricey for a tool like this.

Yes it would. Too bad Sanyo is impossible to get ahold of. I gave up long ago trying to communicate with them.

Ian, are you planning to do a comparison between kprobe and um doc probe? Well maybe only for DVDs should be ok because there hasn't been any way to compare Kprobe results so far.

Thanks for the info and demo link.

Cheers.

No current plans.

[dolphinius_rex]

If someone will buy me the Optorite DVD burner I'll HAPPILY provide some comparisons between the two pieces of software!

About comparisions. For the cd-r there might be something on the way.
At least K-probe(cd-r), Plextools Pro, CD Docter and a CD associates CDA-3000 analyzer will be compared with each other.
For cd-docter and K-probe we are thinking of usseing different Lite On models.

Note: UM Docter II & K-probe meassure different things.
Only PI8 levels might be comparable. However the question remains how much drive dependant these are.

Hey Ian, what's the ruling on acceptable PO errors?

[RJW]

PO=PIF Parity inner Fails which has a Maximum of 4 (1ECC) according to the dvd+r group if I am right.
Your right(I orriginally posted dvd-r group.) it isn't in the dvd-r standard.
Funny thing was that in the first test dvd-r had media that scored below it and all dvd+r media was above it.Meaning it didn't work out with it's own standard.

[jsl]

I don't think max PIF is specified in the DVD-R standard. For DVD+R it's specified to be max 4 (per ECC).

[dolphinius_rex]

okay, so what about when I'm testing at sum 8 ECC?

[RJW]

there isn't.
It's the PI sum(below 280) at 8ECC
and
PIF(below 4 max) and POF(below 1 max) at 1 ECC.
So actually a disc has to be measured twice with K-probe.

[dolphinius_rex]

Okay, so maybe I should be more concerned with the PIF scores, and do more testing at 1ECC... Thanks for the help!

[RJW]

According to C't K-probe tests are useless. More info I will post in 16 hours.

[dolphinius_rex]

So now our only option seems to be UM Doctor Pro II....

Looks like I know what DVD writer to buy next!

[RJW]

Rex if you read C't remarks correct you would know that buying a optorite doesn't help you.

The difference are the other parameters. And the fact that audiodev's pulsetec based analyzer is calibrated. If you got calibration media and now how to program firmware and software then you might solve the Error reading problems. SANYO + LIte ON don't use calibration media to test there drive error retrieval capactity.
