I've got two external hard-drives attached to my PogoPlug, which is then connected to my wireless router to be accessed by two laptops.

I'm using Windows on the laptops...XP on one, Vista on the other.

What I'd *like* to be able to do is sync the drives with each other.  I can use ActiveSync to sync drive A to drive B, but I can't sync drive B back to Drive A.

With them both being attached to the PogoPlug, is there any way to do this?  I looked at SyncToy, but would that work?

I mostly use the XP machine for what I'm doing, the Vista is my son's.

I should probably also mention that I need to keep at least one drive "stable", so it doesn't change names all the time, because I keep all of my music on the external hard-drives and have iTunes directed to that drive.

I can get the PogoPlug to do just about everything I want it to...just can't *quite* figure this last little detail out.

Thanks in advance for any assistance!
