Is that your only copy of that data? If so back it up asap.

If not you can fairly safely run a diskcheck on the external . Bring up explorer and rt click on the external drive andleft click on properties. Go to the Tools tab and click the Check Now button. be sure to check off both scanning options and then click start. Now go see a movie or something, this will take a few hours.
