assign a drive letter to it Device Manager to make it visible.
I am running windows 7 home 64 bit (build 7600). I have a gateway fx7026. It has two internal hard drives. When I look under device manager they are both listed and they are both listed under the bios menu. When I look in my computer though under hard disk drives it only shows the one that I have the OS on. When I had Vista it showed both of them. Is this something I should be worried about. The drives are listed as WDC WD3200AAJS-22B4A0 DRIVE 1 and WDC WD3200AAJS-22B4A0 DRIVE 0.
