The Big KProbe2 Thread

[powaking]

Here's a scan of a 4x +R media burned on a 411@811 using HS0K firmware. Disk was burned at 8x. Burn completed fine but am not able to make a back up of it. It fails to read around 25%. I have 2 other discs that this happened to. I have since changed the media code in the firmware to only burn this disc at 4x. I have since upgraded the firmware to HS0Q (Speed, Read and Booktype hacked as well) and read the disc back with this firmware.

The other discs fail at 39% and 29%. Tried dvd decrypter and Nero. These are the RiData discs I got from Newegg. I wonder if these discs will get better results with the 0Q firmware rather than the 0K firmware.

Here's the ader results of the same disc. Tomorrow I'll throw up scans of the disc that I burned at 4x (same batch of RiData).

RITEKR03s are definitely only good for 4x in Liteon writers. I seriously doubt that any firmware update will change this, which is a shame because a lot of the low cost DVD+R 4x media that you get now is RITEKR03 (Arita, Ritek, Cyq've...). Arita and Cyq've used to be RICOHJPNR01.

- appears +RW issue is fixed: thank you, Karr and Crew!

Question:
...
- Settings to approximate old KProbe 1.1.29 scans would be PISum:8 / POSum:4?

I am hoping for some clarity on this point, what are the settings for PISum and POSum that ppl are using? the default? Or are you trying to approximate the scans from KProbe 1.1.29? If so, are the settings mentioned above correct?

thanks!

How I loved Arita's. Man those discs kicked some butts. Shame that they are close to impossible to find for a reasonable price.

Looks like I'll have to part with these discs to my cousin (who still hasn't done the 411@811 conversion yet :P ).

I'll scan the other disc I burned at 4x and post it up. I'm sure it will be night and day.

rdgrimes (or anyone else for that matter),

We all know about PI/PO results and the ECMA 337 & 338 standards for DVD's, but is there info somewhere that you can point me to, or can anyone tell me off the top of their head, what the max numbers are for CD's (C1 & C2) errors please? I had a look around the ECMA site, but didn't find what I was looking for.

I've never needed KProbe in the past for CD's, but I would like to use it to it's full potential (ie: with CD burns as well as DVD's), only I need the appropriate info to use it properly

Thanks

[rdgrimes]

There aren't any standards for C1/C2 that we know of. But what gets measured as C1 and C2 is not even a certainty, often different errors are actually being reported as one or the other.

But in the most general terms, no C2 ar really acceptable, a disc should read at full speed with no C2.
I have never seen a level of C1 that causes read-back issues. Even levels in the 1000 range seem to be readable.

[bpm]

Thanks for the quick response, mate. WOW!

I have to say that I'm suprised at your response though, but I'll take your word for it

What exactly is the point of being able to test for C1 and C2 errors in KProbe or any other program then?

Experience has taught us that discs with lower error rates are more widely compatable with other drives, and they are less likely to degrade into coasters over time.

[bpm]

I also just wanted to say was a huge thank you to all the posters for the valuable info they share, to the moderators for putting up with a lot sometimes, to the beta testers who do so much so that we can benefit, and particularly to Karr for developing this great tool.

KProbe, along with the info from forums like this, has helped me pull myself up from the depths of having no idea about what I was doing, completely guessing at everything, and burrning complete crap, to developing a great burning system and saving a hell of a lot of money that could have been wasted so easily.

Thanks!!

Version 2.1.0

Change log:

4/29,2004 KProbe2 v2.1.0
--------------------------------------
1. initial start error for external drives
2. Support chart combination
3. Added "Thanks" form
4. fix bug : average and total count won't change when delete highest value

Please note: The program version in the opening post in this thread is always current. The link in this post will function for a day or so only, (due to security considerations). So if this link stops working, just go to the opening post.

I've just noticed the "Interpreting C1/C2 errors (CDR/RW)" link in your signature and read through the post. That's given me the basic idea, although you've said it far more succinctly above

Thanks again!

Here's a scan of the Ritek R03 +R 4x media burned at 4x scanned at 4x. What do you guys make of it? Looks worse than burning it at 8x even though 8x results it not being able to read afterwards.

[powaking]

Here's the same disc with the ader scan. This looks pretty good to me but the PI/PO scan worrys me.

Gosh I get near perfect results using RITEKR03-002 at 4x in my 451@851. My results weren't always perfect though. I found if I clean the surface of the disc with Isopropyl alcohol, before burning, I get a much better result (Arita media).

I'm continuing your ADER discussion here:

Get this, I was able to make an iso of that disc with dvd decrypter. Average read rate was 5.5x with a max read of 8.1x

The scan you see at the top of this page those discs were burned at 8x yet they fail to read between 25-39%. Go figure. Can't understand it myself. Guess all that matters is if I can watch it in the player.

Check out http://www.blankmedia.ca/ . As of tonight, according to their online ordering system, they have almost 4500 pieces of the Arita 4X DVD+R media left (RICOHJPNR01). You can get them for under US$1 per disc in quantity... remember that they are a Canadian company, and the pricing is thus in Canadian dollars.

I have nothing but good things to say about the owners of that business... best place online to order media with guaranteed manufacturer ID's. I have a 50-disc spindle of the Aritas, and they burn extremely well on my LDW-811S at 8X (PI 2.678, PO 0.060 using KProbe 1.1.28... haven't tried KProbe2 yet).

*cough* back to the subject of kprobe2..in case you havent seen you may want to look at these two scans..with a brand new drive. i think they settle the issue on if kprobe 1 is comparable to kprobe2

When trying to install KProbe v2.1.0 under Win98SE I am asked to insert "disk # 2" containing "KP2SETUP2.1.0.2".

It´s not about the two KProbe versions more comparable to each other, it´s more likely some of the bug´s in KProbe2 been fixed, IMO.

And the similarity in your KProbe scans is only a proof your drive is "working" OK.

I got similar result with my third version of KProbe2, (2.1.0).

LOL. Yea, it's a bug with long with Win98 & long directory name, methinks... I saw something similar the last time I was creating an installer...

[fairyliquidizer]

Could you guys help me interpret my scans I am having playback glitches:

http://forum.cdfreaks.com/showthread...threadid=94452

I have used the some of the same media as used in the CDFreaks LG 4040B review but my scans don't look as pretty :-(

Thanks,

no mine definatly was a drive problem not a kprobe one..even my kprobe 1 scans were whacked. now im not saying the 811 is the best scanner out there..i think my PIs are a bit high (due to the lower quality reading of it compared to my old 812 before it started acting up) but at least this drive is consistent. im taking back my 812 and will report back when i get a new one back hopefully it will be as consistent as the 811.

[henasau]

J just installed KProbe2.1. I can't see bottom part of the settings and the status windows.
I am not even able to change the speed setting.
I think this might be related to the larger font I am using.
I am using 1600x1200 resolution so larger font is the necessity for me.
I do have a wish too.
I often test my DVDs in the background.
To save CPU load I minimize the KProbe.
It would be a nice feature to set off some kind of alarm when the test is finished.
