I bought my XPS 9100 back in 2011 as a 500GB Raid 1 configuration. About a year later, one of the drives failed. When the Dell guy came out, he put a new drive in, but didn't restore my Raid 1 configuration. Last summer, my non Raid drive started getting flaky and unreliable. I finally bought 2 WD Black 1TB drives to install in a clean installation as a Raid 1. The drives are in, but win7 can't or won't find or create any partitions I have tried the driver disks and also tried downloading Wd drivers from Dell with no success so far. I know I am missing something , but either I don't know how to tell the Win7 installer where the disk driver is located or I don't know the format in which it is looking for the driver.
Any help would be appreciated.
