Hi Guys


first of thanks for making Img Burn, its my goto program for burning discs.


The question i have may not relate to imgburn but just a general question.


When i burn an iso to disc and then look at the bottom of the disc you can see the part of the disc that has been written too (i have attached an image which shows this) , i was wondering if there was a way i could basically write out the rest of the disc so that it is all the same (so i all looks even)?


I thought finalizing or closing would be the answer but i have tried and failed.


any help would be appreciated

You'd have to pad the ISO to the required size (so it's uses 99% of the disc or whatever) when building it.


You could do that with dummy files etc.

thanks, was hoping to avoid that but if thats what i need to do then so be it

Try this:


Create your data disc using whatever program you like.
Open the DVD Burner window.
(I used Ashampoo Burning Studio 20126)
Add the files that you want to use.
Look to see how much space is left:
i.e. 3gb used
1gb Free

Open up a command prompt
(Right click on Start then Command Prompt)
Create a dummy file to use the free space
enter the following:

echo "This is just a sample line appended to create a big file " > dummy.txt

for /L %i in (1,1,24) do type dummy.txt >> dummy.txt

the parameter 24 creates a 1GB file.

I just copied it and pasted it into the command prompt window.
25 would create a 2GB file.
23 would create a 500mB file.

You will find your file here:
File C:\Users\<yourname>\dummy.txt
You can use copy and paste to create as many files as you wish to fill the required space.
Add the required files to the DVD.
I added dummy.txt (a 1gb dummy file)

Burn the DVD.
It works!
The DVD looks full.

There's a much better / simpler way.


fsutil file createnew dummy.txt




The following would make a 1 GiB dummy file.


fsutil file createnew dummy.bin 1073741824


Now... looking at that thread (specifically, the remark at the top of the actual post you quoted), I can't see it really wouldn't look 'full' if you had a zeroed file. Then again, I've never tried it.


If I wrote 10 files (5 with random data, 5 with zeros) and alternated their names/physical positioning, would my disc come out having 'bands' on the burnt side? I guess that's essentially how LightScribe etc. do their thing.


Having just Googled a few things, it seems as if the laser actually burns (creates bumps / pits) in order to store a 0 and the unburnt area (lack of bump / pit) represents a 1.
