HELP PLZ! 1TB External Harddrive

Good afternoon.  My external harddrive is giving me problems, 3 days ago I transfered some movies from computer to external harddrive, then our power went off, after 4 hours it came on again, so I tried it agan but when I plugged in the harddrive to usb port, the harddrive just making a sound and my computer does not pick it…  I brought it in March 2013 and warrany is in 2015 I think…   What can I do???   

If the power went off while the drive was in use it may be corrupt. Something likeTestDisk   http://www.cgsecurity.org/wiki/TestDisk might fix it if the drive shows in Disk Management.
