Vista - Why doesnt it like the Intel Raid drivers - wont install

I'm trying to load a clean install of Vista 64 onto a Raptor HDD but keep getting Windows could not retrieve info about the disks on this computer error AFTER pointing it to the (64bit) driver. This is a brand new drive that I have added to my Asus P5K-E PC and Vista certainly sees it (giving me details about it, and has formatted it) even the HDD light glows. I have disconnected the other 4 drives that will be again Raid 0 pairs once I have Os on. BIOS is set to RAID.

Now I'm still confused if I need to load a RAID (SATA) driver during install (you certainly have to in XP - I load the Intel IH9CR and the JMicron E-Sata drivers from floppy) but it seemed a good idea to get the latest drivers in there... But it then doesnt see the HDD after it loads the Intel driver drive from Floppy.

I am progressing with the install WITHOUT the latest drivers, and all seems OK, but I am concerned that I've cut a corner on what is a very important performance critical editing system that I dont want to rebuild again

Any thoughts guys?

Thanks

PS damn this Raptor is noisy!!!!!
