My understanding is the follows
Ghost 2003 = Ghost 8.0 ... this was both windows based and included dos version....this is the one I have and use. Note, I only use the dos portion....it works like a champ
Ghost 2004 don't exist AFAIK, unless this is what sechs meant by Ghost 8.5. I know symantec released updates (mostly compatibility with burners I think) for ghost 2003, so maybe this is what he has or means
Gost 2005 (if such a thing exists) = Ghost 9.0 ... which in the rehashed Drive Image, but comes with Ghost 2003 (both the windows and dos versions?)
