Sometimes CDs are scratched and the LOGO starts (with delay) then the menu shows up (delays) and at times, booting one item works while other doesn't as IM* or BIN etc images in BOOT folder is unreadable due to physical scratches. I was suggesting that "boot" folder gets physically copied xx times in physical disc (xx is set by creator of ISO). It means Boot folder can be copied once in the begining then in the middle and at the end of the physical disc. (I'm saying begining + middle + center which means xx=3).
Scratchless EZBoot ISO usually boots in approx 1 to 2 seconds but if EZB emulator detects boot failure due to read error in the 3rd second, it should select different backed up location from middle or end of physical disc.
Because in future storage medium has more GBs (HD DVDs+BlueRay+DVD-DL) EZB should allow not only copies of BOOT folder but entire project build (thus making disc xx times secure from scratches). I would be really thankful if you (developers) understood little part of insurance backing concept.
