Hello all , this is my first post , i have the same problem like "kyr" (i have slipstreamed successfully mass storage 7.04 , and my hard drive still cannot be detected). First i want to tell u that i had done the same disk 6,7 months ago , i installed it on my pc without any problems . I suppose it`s somthing from the Driver pack cuz i do everything the same way . Does anyone know how to download older version of the Mass storage driver pack ?
