Added SATA Drive appears as Mobile Device in My Computer

Hello,

I had added an IDE drive to my Dell E310 in the spot reserved for a floppy drive without any problems. I decided to upgrade, so I removed the IDE and put in a second SATA drive. When I boot up the computer recognizes it as a Mobile Device. I went through the control panel to format the drive, but the only option I have is to Initialize. I did this, but it did not change from a Mobile Device. How do I get this drive recognized as an Internal Hard Drive?

thanks,
