All you need is this:
it will install the RST App and drivers for your RAID if your RAID is setup on the blue SATA ports.
No uninstalling/cleaning of any previous drivers I have installed? I noticed the setup said something about uninstalling older driver, that's enough?
Nope just install it and reboot.
The iastorv.sys driver is just the default Intel packed driver that comes will windows so that when you install Windows you don't need to load any drivers. The iastor.sys is the newer driver that gets used over the iastorv.sys driver when you installed RST.
Thank you, that clears things up on both files! Now lets see what happens. If I don't forget, I'll get back to this thread to let you know once I'm confident this issue has been resolved.
