Thanks. I am not very familiar with the file handling operator.Actually, I want to read and copy the hard disk by sector. I am trying to use this function.
DrvHndl=CreateFile ("\\.\C:", GENERIC_READ + GENERIC_WRITE, FILE_SHARE_READ + FILE_SHARE_WRITE, lpSecurityAttributes, OPEN_EXISTING, ByVal FILE_FLAG_NO_BUFFERING, 0&). Does this function helps to read and copy the hard disk. I don't have much idea about these function. Please help....
