LazLong Posted March 25, 2009 Share Posted March 25, 2009 What is the methodology used by ImgBurn's verification process? i.e. when I put ImgBurn into 'Verify' mode and select a .dvd/.iso/etc file, how does ImgBurn compare the image to the disc? I assume it is a byte comparison; I'm curious how ImgBurn takes an .iso file and decides how to map it to the sectors on an optical disc in order to perform the comparison. I'm not looking for a detailed, low-level description, just a brief "here n00b, read this" or some such. Thanx! Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted March 25, 2009 Share Posted March 25, 2009 An ISO is a complete disc image. So if the sector size on a disc is 2048 bytes, it reads 2048 bytes from the file and compares it to sector 0 on the disc. Then it moves onto the next sector.
