As there aren't such method exposed by VDS itself, I don't think it's possible for now.
Haven't checked the new Storage Management API introduced in Win8/Server 2012, but since you're using Win7 that's not relevent.
EDIT: So you're manually editing the bits to make it look like as if it's connected again? Just make sure you also run SMART check when you have free time. I've used software mirror feature in Win2003 for many years without problem, so I don't think they'll break just because of unclean restart. You should run a health check just to make sure your disk set is reliable.
