Hi
If the recovery partition is filling up it is likely a automated backup program is backing up the C: (Windows) drive to d:
see
http://windows.microsoft.com/en-gb/windows/back-up-files#1TC=windows-7
this referrs to Windows 7 but Vista has similar backup software

You should be backing up to an external hard disk not the main hard disk
You have to be careful to distinguish the folders & files which are part of the recovery system and those which have been put there by the backup program
Stop the backup process until you find the configuration options
You need to find out from Gateway documentation what files & folders should be there on D:
Have you got a set of Vista recovery DVD's?
If not make a set
