Computer trying to access WD external drive

Portable Drives My Passport

Have just purchased and installed WD external drive.  When the external drive is not connected to the computer, the computer tries every 2 minutes to access the WD external drive.  How can I keep the computer from trying to access the WD external drive that is not connected?

Hi, how do you know that the computer is trying to access a hard drive that is not connected?
