I'm having problems with my toshiba laptop getting too hot and shutting down and looking to take into a certified service center. To date used disk space on it is a little over 57 gigs. Could I use GHOST and then link up my desktop pc with my laptop via ethernet and put the Ghost Image on my larger hd on my desktop system? I'm not sure of the innner workinga or particulars of GHOST. With more then likely having to take this thing in..i'd prefer to back up using the mentioned idea instead of going out and having bo purchase and external dvd burner. Any at all help and hints in the right direction would be great.
