Some of us have been given the chance to play with the newest offering from CDSpeed, version 2.94 which will enable PI/PO scanning on supporting drives.

This thread is for posting results and reporting problems and/or suggestions to the author.

WE are not able to distribute the program, so please don't ask for it!

The new version of CDSpeed now offers error scanning only on those drives that support it, and also included jitter testing as well.

Which drives actually work will be posted here as time goes by and we have a chance to test them.
Feel free to jump in and ask questions or offer feedback and suggestions.

I'll start off by reporting that LiteOn drives seem to be working fine in CDSPeed. Here's a comparison scan on the same crappy Ritek R03 disc burned at 8x.





As you can see, the scans are very similar. Although the numbers are a bit different. I don't know what ECC-sum settings the program uses, but I'm guessing 8/1 just like Kprobe2.

Here's a Ritek G04 burned at 8x:

You have "show jitter" checked but no jitter results???

That's drive specific, LiteOn does not support it but the NuTech drives do.

Suggestion:

Autoscale the graphs. Easier to see the detail.

I can confirm it doesnt work with Toshiba drives, at least the SD-R5112. Got this while trying:



I will try with a Plextor 708 drive later on tonight, will post results if any.

Too buggy yet.

With my 812S I could select Max, 7x and 437x!!. And there is no information on what the PI/PO sum settings are.

With NU DDW-082 it's not possible to get CLV results.

And the NU reports MUCH higher error amounts than the Lite-On 812S at least!!!

It can't be PI 8 as it's impossible to have more than 1664 PI errors......look at the pic below (yes I'll set it to auto scale next time). Can't Be PO 1 either as that would be 208 max.....

Works with BTC DRW1108IM as well....... (testing now).

How about NEC 2500A? Has anybody tried on it?

Doesn't work.

"Error initializing test"

Already available, autoscale or adjustable fixed.

fine tease us with your new toys..Hey i have toys too!!

have you tried it with a benq drive like the 822?

Wonder if that is a problem with the Nu drive. CDSpeed can't really create errors, just report what the drive says, so the drive might be to blame. Trying it on a better disc might help.
I'll have a Nu 082 in a couple days to try it with.

Here's a Ricoh JPNR-01 burned at 8x, I used the auto-scaling this time.

I wish there was a "save to image" function!

there is its the upper disk icon on the title bar.

Can you try this on your DW-822?

"Error initializing test"

So what determines if a drive supports it?
Hardware, Firmware or a combination of both?

The chipset must support reporting, and the firmware must also enable it.

Unfortunately, saving as bitmap is of little use, we need GIF or PNG format. As I recall, there was a way for CDSpeed to save as JPG or GIF, but some other tool needed to be installed.

So with the NU and the BenQ both being based on the Nexperia chip the BenQ should support this if the firmware was updated?

I thought I read somewhere a while back that BenQ was going to provide some PI/PO measuring tools. Anyone remember seeing that?

I'm not sure but I thought BTC = MediaTek, BenQ = nexperia indeed.

It saved it as png here at my computer..... (didn't change anything - it did that as default).

The settings are in "options", but I get error messages instead of a choice. I recall some documentation on this somewhere.

OK, I figured it out, you have to copy that file to the directory that CDSpeed is located in. Works nice now.
