There is no DOS under WinXP and DOS would not be able
to access a dynamic disk anyway. To make the partition visible
under "My Computer" you must assign a drive letter to it. Click
Start / Run, then type diskmgmt.msc {OK}. When you
right-click the "invisible" partition then you get the opportunity to
do this.

You can now back up your data to some other medium.
