XPS8700 doesn't recognize ULTRA II 480G

My Dell XPS8700 desktop doesn’t recognize my Sandisk Ultra II 480G SSD.  I am running Win 8.1.  The Sandisk SSD Dashboard can’t find the SSD.  It is connected to the SATA port 2 and I have checked the power and SATA connectors.  Any ideas?


did you format the ssd inside the disk managment in order to initialize the drive and create the partitions on it since all the ssds come unformatted and you need to format them before using them normally on the computer. 

I tried to format the SSD using a USB connector and it still was not recognized.  Thanks for the suggestion because now I know the SSD was DOA and I’m sending it back.
