Hi Guys Just joined today, Im hoping im in the right section, I have a vista columbus VDGHD hard drive recorder, and it obviously has a hard drive to record, the problem is it is 15GB and columbus have told me it can take up to 100GB, but need to clone the HD by ghosting it onto another Hard drive, tried this on a windows XP machine with ghost but didnt even find the hard drive, any ideas would be appreciated Thanks Jon
