I've experienced the issue with a 4-drive RAID-5 on the ICH8R. From
what I can tell, the Vista installation environment does a low-level
write to the disks in a control block during its start-up that corrupts
the RAID array. When it happens on my system, two drives get corrupted.
The first drive needs to be rebuild but the second just needs to be
reset. Given the behavior, it's not surprising that users have no
problem with RAID-0; in that configuration the two disks don't match
but each is okay. With higher levels, the disk is actually corrupted
and fails.
I have been able to get Vista working on the RAID array by installing
on a single, non-RAID drive and then cloning it with Norton Ghost 12 to
the array. However, I end up with drive letter problems because the
drive letters in use point to the original partition. I think I know
how to resolve that issue but haven't gotten around to it.
Both Microsoft and Intel seem disinterested in the issue which is
either with the driver or installation environment.
