I am not sure the fdisk would work at all that way, but it might. Also, I wouldn't guarantee that the current contents of those slices would still be usable. They might. Doing an fdisk only modifies the slice table and not any of the data or even the partition tables for the slices which are written by bsdlabel. So, it might leave it intact. But, if you are up to experimenting, you might learn something. If you have a good backup of what you need to preserve, then the worse that could happen is you would have to start over from scratch and reinstall both Vista and FreeBSD. At that point, it becomes moot because you can put things where you want. ////jerry > > > - -- > > Aryeh M.
