MDT logs say they copy drivers, but cant see it and it does not install

Hi All

Why does my MDT 2012 update 1 never install drivers when I use my customized image? I use the same task sequence and replace the OS with source files from the disk and the drivers install fine.

ZTIDrivers.log shows the drivers being copied but when the ts is done I cannot find C:\Drivers and no drivers is installed.

PLEASE HELP
