Thread: .iso's are not same size after burn?

    .iso's are not same size after burn?

    I burned the new RH8.0 and while the .iso's were around 662megs each when I burned them to CD it took up less room. Does this mean that the .iso's are going to be bad on the CD or is it just a wierd mathmatical thing when the one program calculates file size.

    I burned them as .iso and disk at once instead of track at once.

    Re:.iso's are not same size after burn?

    The iso will contain more info than just what is burned, like track layout, and yadda yadda yadda. So a 700MB iso can be a 650MB cd very easily.

    To verify a cd image like an iso, use md5sum to verify the MD5 hash from what the supplier shows. Calculating an MD5 will take several minutes on a file as large as most isos, but will save you the headach of bad burns.
