I/O Buffer size

Are you sure the resulting image was only 90mb?

 

What does the calculated size come out to? There's a lot of slack space involved with burning little files.

 

ie. 2049 bytes of file data is 2 sectors (4096 bytes).

 

90 meg of pure image file data would of course fit in a 128 meg buffer.

You're absolutely right, there's a lot of slack space involved :

 

Size of the directory 85,8 MB (90.011.590 bytes)

 

Size of the directory on disk 928 MB (973.651.968 bytes)

 

and i created and Iso of the same directory --> Test.iso = 281 MB (295.108.608 bytes)

 

Btw with this memory :

 

Total Physical Memory: 1.048.048 KB - Available: 701.908 KB

 

And without using other programs when ImgBurn is burning, is it possible/safe to assing an I/O Buffer of 256Mb instead of 128Mb, to try to avoid buffer underruns when burning directories with small files (obviously much less files than in the test).

 

Thank you very much.
