Burnspeed is not what is selected

[kostenzer]

I selected burnspeed 1x

But the burningprocess is 6x

 

 

I would say if you can select burnspeed 1x it must burn with that speed.

[cornholio7]

you need to look at what the supported speeds are, in write mode in the right hand panel you can see what the supported speeds are

it will only burn at a supported write speed

[Shamus_McFartfinger]

I selected burnspeed 1x

 

 

I would say if you can select burnspeed 1x it must burn with that speed.

 

And you'd be wrong. ImgBurn has nothing to do with speed selection if it isn't supported by the media. If you post a logfile, we can show you why.

 

Help Menu > ImgBurn Log

[spinningwheel]

Supported Write Speeds: 4x; 6x; 8x; 12x; 16x; 18x; 20x

 

 

You can't get 1X out of a disc that says 4X is the slowest it will work. The drive cannot be forced to work at a speed not acceptable to the disc manufacturer.

[mmalves]

Slower doesn't always mean a better burn. Please post a log as Shamus said and we might be able to tell you how to get better burns

[IntelInside]

Supported Write Speeds: 4x; 6x; 8x; 12x; 16x; 18x; 20x

 

You can't get 1X out of a disc that says 4X is the slowest it will work. The drive cannot be forced to work at a speed not acceptable to the disc manufacturer.

 

Just on this, ImgBurn rates my TDK DVD-R disks at: "Supported Write Speeds: 6x, 8x, 12x, 16x" whereas the container they came in states "1-16x speed v2.1 rev.6.0".

 

Consequently, like the OP, when I selected 1x write speed the actual write speed was logged as "Average Write Rate: 8,086 KB/s (5.8x) - Maximum Write Rate: 8,428 KB/s (6.1x)"

 

[FYI: I want to burn the Win7 RC at 1x speed for reliability reasons]

[LIGHTNING UK!]

If you want a reliable burn, buy decent discs.

 

As you already know, your drive doesn't support your discs at 1x. 6x is the lowest it'll go.

[Guzeppi]

Just being pedantic really.

 

Does the container actually say "Burn" or "Write" at 1X - 16X?

 

Because, if not they're not actually lying. It can be "read" at 1x after it's burned.

And I want to report my own experience too with ImgBurn 2.4.4.0. I just burned a disc at a high speed when I wanted it to be burned at 2.4x

As you can see, speed 2.4 is supported by the media, yet ImgBurn burns the disc at a higher speed (please note the maximum speed used!), so buffer overflows happened.

Why this? I selected the lowest speed so I could do something else while burning but this did lead me to wait for buffers to recover...

It's becuase your drive does not really support the media you are using.. Right click on your drive in ImgBurn and click check for firmware update, if you find one update drive... Take any disc form drive and keep tray closed or read any read me that describes update process

 

 

2.4x is not a valid speed for dvd-r

[topolinik]

2.4x is not a valid speed for dvd-r

I didn't know this...

 

Anyway, in such cases it would be helpful for ImgBurn to warn the user that selected speed cannot be used.

And it would be VERY nice if ImgBurn selected by itself the closest speed available (4x, in this case) according to the media capabilities.

[LIGHTNING UK!]

Your drive should have burnt at whatever it supported that was close to 2.4x.

 

If you burn another disc, press F8 (to enable Debug mode) before clicking the Write button and then save the log to a file and upload it.

 

I'll then tell you what speed the drive thought it was burning at - or why it rejected the commands used to set the speed.

[captainvideo]

I also noticed the same thing since I upgraded to the latest version of ImgBurn.

 

I have been using Fuji DVD+R (1 to 16x). ImgBurn gives supported write speeds of 4x; 8x; 12x; 16x.

 

I select 8x but it burns at 6x which is not even supported.

 

Any ideas?

[LIGHTNING UK!]

The update is not the problem.

 

Are you sure it doesn't just start at 6x? A lot of drives do that before moving up to 8x.

 

The other thing to check for is that the buffers are full all the time.

 

If the drive doesn't even list 6x as a supported speed then there's no way ImgBurn can tell it to write at it. Even if you tried, the drive would simply ignore the request and apply fuzzy logic to it to reach the next one it DOES support.

No, it stays at 6x for the duration of the burn. And the buffers are full all the time.

 

This only happened after upgrading to the latest release of ImgBurn. Before then, these same blanks burned at 8x.

 

After the blank DVD+R is loaded, a screen appears on the right showing the supported write speeds. 6x is not listed among them. Even though I select 8x, it burns at 6x according to the screen.

 

And I am able to burn CD-Rs at 8x via ImgBurn's cue file method.

 

This is strange but not of any major concern to me since all my burns complete successfully. If fact, I cannot recall having a single burn failure since I began using ImgBurn last year. And I burn DVD+R DL in addition to DVD+RW, DVD+R, and CD-R.

[LIGHTNING UK!]

Do the other 'supported' speeds burn at the proper speed?

[mmalves]

Do you have Daemon Tools or Alcohol 120%?

[captainvideo]

Do the other 'supported' speeds burn at the proper speed?

 

Lightning UK:

 

I burn DVD+R DL and DVD+RW at a supported speed of 2.4x.

 

I burn CD-R at 8x and CD-RW at 4x.

 

All these supported speeds burn at the proper speed.

 

It is only the Fuji DVD+R which burn at an "unsupported" speed of 6x instead of the supported speed of 8x now. But it did burn at 8x prior to the latest release of ImgBurn.

 

I know the maximum supported speed of the Fuji is 16x. I forgot whether 12x is also supported. I am kind of leery about burning at such high speeds.

 

Most of my DVD burns are DL. The next time I burn a SL, I'll post a copy of the burn log here.

Can you burn a disc that the source file is more "filling up" the disc? You could use the Discovery mode to burn the whole discs capacity.

 

This burns source was only 1,447,892 and it might be that the burner doesn't catch up the 8x speed until the later part of the disc.

 

The burn you did with the same media and the old version of the program - was that with the same amount of sectors for the source image?

 

If you enable the option to save a graphical file over the write/burn speed - can you also post that file?

 

Edit: Noticed that the first post in this thread is more or less a burn with full disc capacity - so forget the above.

 

[LIGHTNING UK!]

I'd still like to see a LOG/IBG file from a full disc burn - where the full disc is burnt in Discovery mode.

 

I'd also like to see the disc info from when you're in Write mode please.

[topolinik]

2.4x is not a valid speed for dvd-r

Well, something strange is happening...

I just tryed burning another disc, setting for 2.4x speed and now... it worked! Speed was constant during the whole process and i was able to surf the web, launch a pdf viewer, edit a text file and so on.

 

If you burn another disc, press F8 (to enable Debug mode) before clicking the Write button and then save the log to a file and upload it.

Here you have it attached.

 

Edit: the only small thing I can see is a difference between the content of the two discs. The former (speed selection dishonoured) was a video DVD, the latter (speed selection honored) is a backup of AVI files, ImgBurn called it a "DivX disc".

Cynthia:

 

I am one of two people who have been sharing this thread about the burn speed.

 

I am not familiar with the Discovery Mode and do not wish to play with the disc's capacity.

 

I have burned several Fuji 16x DVD+Rs with varying ISO file sizes. Some have been over 4gb but this one turned out to be smaller.

 

It makes no difference. I have always seen a Write Rate of 6.0x for this media since installing the latest version of ImgBurn. Even though I selected a supported rate of 8.0x (which is half of the max).

 

All my burns have been successful, so I am not losing any sleep over this discrepancy.

 

Any other ideas, please let me know.

captainvideo,

 

Do as I asked in my previous post please.

 

Discovery mode just generates a virtual image in memory and burns it. It rules out certain external factors.

 

It really just burns zeroes to a user specified number of sectors on the disc, that's all. It won't have any effect on your future burns (if you were worried about the whole 'capacity' thing).

Explain to me how to use the Discovery Mode and I'll try it the next time I do a SL burn (which is not often. Most of my archiving is DL). It might be a while.

 

Thanks!
