Your data disc 'b' may have been formatted as a dynamic disc, as opposed to
a basic disc - the gist of which (I believe) means you'd need to reinstall
XP on your 'a' disc (or a partition of it) to gain access to your data. You
could perhaps shrink down your Vista Partition to achieve that / put an XP
partition on it.
