Verifying Burn Question.

[Anthony1uk]

I have just downloaded Imgburn 2.0.

 

And I have a very quick question. I have done a forum search but cant seem to find the answer to this.

 

But could I enquire how exactly does imgburn verify the disk after burn is completed.

 

For example it do what Nero CD/DVD speed's error checking feature does and look for PI-Errors above 280 to deem a coaster or does it do something completely different.

 

Or does it make a MD5 checksum calculation of the original image and compare this to a MD5 checksum calculation of the burned disk (if i have understood MD5 checksum comparisons correctly, i would really love this feature to be included to imgburn if it does not currently offer this).

 

But i am just curious as to what exaclty it means if an burned image verifies Ok. Does this mean it is a perfect faultess burn and therefore doing a burn error scan in Nero CD/DVD speed to check for PIF's and PIE's is not neccissary.

 

Thanks

It does a bit by bit comparison against the original image file.

 

So at that point in time, the drive can read back exactly what has been written and the two match 100%.

 

A PI/PO scan will then pretty much tell you how difficult is was for the drive to return that 'correct' (or if you're unlucky 'incorrect') data.
