I just got a Dell 8300 XPS. When I try to disconnect my Seagate free-agent go external drive, I keep getting a error message that the device is still in use (even though it's not). I did not have the problem with both my other HP Win 7 computers. I have read and tried several trouble shooting methods that I have read,and stiff cannot get it fixed. Also,when I try to uninstall the driver,the box is not "highlighted" so I cannot do that function. Autoplay comes on when it is connected and I am able to open it with no problem..it's just the disconnecting that is driving me crazy!
