Negative.  Ghost is as capapble of making a bitwise copy of a drive (one of
two modes it has) as is dd in *NIX.  It is perfectly admissable in all
courts I know, as long as it is done quickly after compromise.  Standard
procedure (as little as there is standard in this young but quickly maturing
field) dictates you make an immediate initial dd copy for the court.  Then
make as many working dd's as neccessary for forensics.

Under most jurisdictions, an ordinary disk image produced by Norton Ghost
etc
using standard hardware is completely inadmissible in court, as it is
impossible to make one without possibly compromising the integrity of the
evidence. The police etc use specialised hardware for making such copies,
which ensures that the disk can't have been altered.
