Slow Verify speed

[c4fen01r]

I have a pioneer dvr-112d with the last firmware (1.22) and have set the veify speed at MAX in the settings menu.

I use verifying my dvds after burning them (verify option enabled).

 

The problem is that after reaching about 7.0X speed, at about 30% of the veifying process the speed suddenly decreases to 2,0X, till the end of the process (meaning that I have to wait forever for the process to complete...).

 

I remember that with my previous NEC the verify speed was a lot faster.

Any solutions?

 

Thanks in advance.

Are you using decent media?

 

Post a copy of the IBG (graph data) file displayed in DVDInfoPro as a pretty graph.

Thanks for replying me.

I only use Verbatim dvd-r

Please can you explain what should I do with DVDInfoPro? Maybe insert an already burnt dvd and select "read burn info from media", then go to IBG?

Can you post a log from ImgBurn

You can find them by pressing HELP and choose Logs and the graph data is just above and will open where they save to.

You should then arrange by modified and use the last one listed

I don't have any graph data (the directory is empty).

Anyhow, this is the log of my latest burn:

Apparently the pio 112 does not like these disc's much.

Be thankful you can actually burn to them as others have trouble, if it actually verifies then the data is good.

Until another firmware update addresses the issues with those particular disc's maybe try and get some verbatim TYG03 or some verbatim 8x media.

 

Also burn them at 12x or higher

[LIGHTNING UK!]

You should enable the 'Auto Export Graph Data' option in the settings.

 

Or when you've finished a burn, do it manually via the 'File' menu option.

 

You can also press the black disc shaped icon/button (with a blue 'i' on it) to have it go directly to DVDInfoPro.

 

If you enable auto export, you can double click the log entry to have it bring up the graph automatically in DVDInfoPro.

 

What are the buffers at when you do a verify? I assume the Image one is full and the Device one is empty?

If I knew this, I would have bought a new NEC, instead of a Pioneer, since with my old NEC I didn't have such a problem

 

I'm curious about your suggestions... Is Verbatim 8x better than Verbatim 16x, that I actually use?

 

And as regard with burn speed, I always burn at 4x since I thought that slower speed ---> better result

Am I wrong?

Thanks, I'll try it at my next burn.

I didn't pay attention to it... sorry. Something else to look at for my next burn / verify

[dontasciime]

I meant 8x or higher

[c4fen01r]

New burn/verify attempt.

I changed the hd where I stored the ISO... this time it was my primary hd, a Seagate SATA, a little older and slower than my other one...

Incredibly, it seems that changing the hd solved my problem!

Perhaps it just needed defragging?

Nice suggestion

[dontasciime]

and check it for file system errors
