Thanks for all the replies.  I have spent the day in deep research and I have learned some crazy things about how Dell builds PC's.   I checked the Bios settings through two different page views.  Both clearly show there are only 2 SATA drive inputs. [IMAGE]System Info View[IMAGE]Drives View I learned that Dell uses the same basic MB, but builds it differently based on what it goes into, without changing the MB name.  This board, MIH61R, was used in the Inspiron 620, the Optiplex 390 and the Optiplex 3010 (at least).  Based on the pictures I took of my screen, I have an Optiplex 3010 MB.  As I continued searching for a way to get the other two SATA inputs to show, I came across this 2 page post on my exact topic. [URL] His pictures looked just like mine, but in one of the replies on page 2, was this chart: [IMAGE]See The Right Side Column This board, as used in the Optiplex 3010 has 4 SATA inputs, but Only SATA-0 and SATA-1 are active. SATA inputs 2 and 3 are disabled by design. Fortunately, for me, the home builder has agreed to refund my money when I bring it back to his home. Hopefully that return will go smoothly. I am never getting near a Dell MB again.    
I purchased a new basic build that used the Inspiron 620 MB, Dell MIH61R .  I was told there were 4 SATA inputs on the MB. I did not know that Dell has only 2 configured for data HDD's.  The two black SATA inputs are for a DVD drive and another Optical drive.  Is there any way to change these to additional data ports?   I have a 250 GB SSD in the SATA 0 to boot.  A 2 TB HDD in SATA 2.  I have two more 2 TB HDD's we need for storage. Any instructions on re-configuring the optical SATA inputs to regular data SATA inputs is greatly appreciated. If is not possible to re-assign the inputs, do you know any other way to hook the two additional drives up?  I have never had a pc that could only accept 2 drives. Thanks in advance for your help.    
Dell MIH61R MB in a new generic build. Can SATA Inputs Be Re-Assigned?
