Ask the f-list

When using the Intel Matrix Storage Console (7.8, if it matters) on XP and trying to get a RAID 1 configuration set up using an existing drive (which I most emphatically do NOT want to wipe), does anyone know how to get it to tell me something just a bit more more useful than simply "Volume creation failed"? You know, like maybe WHY or HOW it failed? The documentation in this area is about as helpful as the software itself.
