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 might fix it if the drive shows in Disk Management.


If done the testdisc and it dont show my harddrive…:cry:
