How do I perform the Quality test?

I read through the guide and here is what I was able to do…

Anyone know why there are those drops?

I first went to Create Disc and burned a DVD+R at 16x, then scanned it, then I went to benchmark…

I goto Disc Quality and the start button is grayed out…

Are these results good? I have no idea what to compare it to really…

Thank you in advance and sorry again for my ignorance. :sad:

There’s instructions on how to un-block the Samsung somewhere around here, but I don’t know where. Here’s a .reg file if you just want to do it automatically.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Ahead\Nero Toolkit\CD Speed\CD Quality]

And those drops are WOPC.

Walking Optimal Power Control: the drive checks the disc throughout the burn process in order to determine whether or not to raise/lower the laser power [and other adjustments]. [The drive may also drop its speed if it determines the burn process isn’t going so well]. Each dip is the drive checking the disc [which requires a temporary pause in the data flow].

Unblock what? lol… sorry maybe I’m just really dumb?

Some drives are blocked from scanning with CD-DVD Speed for various reasons. [In this case, it’s purely historical, as some older Samsungs didn’t have the capability to scan]. These drives can scan. Using the .reg file would allow you to use the drive to scan with CD-DVD Speed.

Ah, I see… so I download that REG and run it, then I can scan!

Also, I’m using DVD Decrypter to rip DVDs… is it a good program?

I’m gonna rip it, then burn a copy and scan it!

Well, that’s my plan at least… I wanna see the difference of burning at 16,18,and 20x speeds on a verbatim 16x DVD+R.

Err… I ran the reg key and the start button is still grayed in the Disc Quality tab?

Hmm… wonder why. Sorry.

Anyway, try opening regedit and manually modifying the data for the “blocked” key. Remove Samsung and TSSTcorp from the list.

Yea, they are gone from the “blocked” key… Still no Quality test start button :sad:

you have to reboot

not sure what windows he is using, but that reg key will only work on 32bit

For Nero 8 :

Did anyone catch his burst rate? 166MB/s? :eek: :eek:

100 more than i get with eSATA :doh: :bigsmile:

must be one the new sata 1.1 drives(150+15) drives

How do I unlock the CD speed quality test for the SH-203B in Vista Ultimate 64?
The reg file included in this thread, did not unlock the Quality scan in Nero CD-DVD Speed.

Any help would be appreciated.



I got this from a link here, can’t find the link tho

Maybe from this link?

I have Vista Home Premium 32 and have searched the registry for
Toolkit and did not see any entries about “blocked”. The start button
is not enabled for me either in Nero DiscSpeed 4 from Nero8.

I see:

HKEY_CURRENT_USER\Software\Nero\Nero8\Nero Toolkit\DriveSpeed

and my two drivess: ATAPI DVD A DH16A1L

Each entry has default, DVD Speed List, Speed and Speed List.

HKEY_LOCAL_MACHINE\SOFTWARE\Nero\Nero8\Nero Toolkit\DiscSpeed\CD Quality

credit this time to LuK who may have gotten it here
