LazLong Posted March 25, 2009 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!
LIGHTNING UK! Posted March 25, 2009 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.
