My HDD partitions currently look like this:



I would like to shrink the Vista partition and add the space onto the XP partition.

I know Vista has it's own partition software 'Shrink volume'.

Firstly I assume that this shrink volume can do what I want to do, can it? Secondly if I do this then is there any chance of me losing data from any part of my hard drive? There's always people who mess up partitions, but ignoring them, should this be a straight forward risk-free process?

Thanks.
