I want to install bigger hard drive in my optiplex gx280 but when i hook it up it says the drive isn't found. What do i do?

Can you be more specific. You are installing a new drive and how does the computer tell you that the drive is not found?
Almost sounds like you took out the OS drive and replaced it with a blank drive.
