Spanned Volume on two dynamic disks XP->Vista

Hi,

A couple of days the main harddisk of my computer crashed. On that computer
I had next to the main harddisk a spanned volume on two other dynamic disks.
I took the opartunity to buy a new computer and installed vista ultimate
(which should support dynamic disks right?) But nada, no spanned volume in
vista. I see both disks in the diskmanagement, they are recognised as being
dynamic but they have the label "offline". When I click reactivate it tells
it is not possible because of unvalid parameters.

Is there anything I can do to attach this spanned volume to my computer? I
really dont want to loose its content...

I have a dutch version of windows, so some translations might be wrong and
the english version would use other terms...

Many thanks,

Liewe
