You use a commandline switch -split=0 which will help you to create just 1 .gho file instead of spanned files .........................
* Command line can be used on Ghost Cast Server.
* Command line can be added to the batch file which is start.bat on the last line after starting ghost32.exe.
* Can be included after booting the machine to ghost.
Select Quit.
Change the directory to X:/ghost (WINPE) or C:/ghost (PC-DOS).
Type ghost32.exe -split=0.
* IF you are using ghost console then open the properties of task and switch -split=0 can be added to advanced.
Let me know if it helps.
