I would say that probably depends a lot on the partinioning, if you have 
a single monolithic partition, you might be ok. If like me you like to 
make a lot of smaller partitions on a large disk, you're fscked. In the 
first case it will bite you anyway at some point. I doubt mirroring 
changes anything. Disk geom will depend on bios anyway and there's no 
way you can be sure it will remain the same.

At least W2k has a very serious problem with reshuffling the disk 
partition names when moved from box to box, or even on the same box on a 
different channel, hell even on the same damn channel if you 
reinstall... I've done this a lot and it kills all your paths when you 
make sample based audio for example.

To the best of my knowledge this was *never* addressed, I doubt XP did 
anything to that effect.
