If it is a brand new drive it needs to be initialized then formatted before Explorer or My Computer will display it. Right-click on the "My Computer" icon and select "Manage" then "Disk Management." You should get a prompt that a new drive has been detected. Follow the instructions to initialize it then format it to NTFS. After that it will show up normally.
