The two most common problems are: Missing RAID controller drive OR you simply forgot to initialize the hard drive

Not Recognized Due To Missing RAID Controller Driver

If you do not install the correct driver, the RAID Controller will not be recognized properly

1. Step Open the Device Manager – hit Windows key + R and copy and paste this: devmgmt.msc and hit Enter

If Windows 7 does not have a proper drive your RAID it will not be able to recognize it and therefore you would end up with this:

2. Step Right-click on RAID Controller and click Properties, then check the General tab for further information. It says This device is not configured correctly

This Device Is Not Configured Correctly

3. Step Go to the tab Driver and click the button Update Driver

5. Step Now comes the bad part – finding your drive! What motherboard do you have? Check our list of places where to download RAID controller drivers

You will have to download the correct driver for your OS e.g. 32-bit or 64-bit. Keep in mind the driver may also include the label AHCI – some manufacturers bundle AHCI and RAID drivers

6. Step Look for a file *.inf – e.g. ahcix64.inf
