UP until now, when I burned a CD/DVD from an iso file, the sizes were the same. I.e. after burning Win7, the used space and iso file size is the same. I have an iso file and a CD where this is not the case. As far as I can tell, the CD is okay. If I build an iso from the CD, the size of the iso is 1,245,184. If I take that iso and reburn the cd, the used space shows 1,226,752. I don't understand the loss off 18,432 bytes.
If I mount the CD with IMGBurn or ISOBuster, they show the same size as the iso. Anyone know what is causing windows to see less on the media in this case?
I often use crc305.exe to check the media against its' iso for verification. This is how I noticed the size difference. Windows properties from the CD shows the same size as crc305.
