Is the drive shown as G:\ in Windows Explorer? When was the last time you successfully backed up with OneCare to the drive?
Sometimes, when you unplug the drive and then plug it back in, Wndows will assign it a new drive letter.
At this point, I suggest resetting the backup plan after confirming that you can access the external drive.
