Hello and welcome Kishor now I have gut feeling that drive night have been damaged by the sudden power failure it could have affected the platters themselves or the controller unit.
Now I think you need to test the drive using this SeaTools for Windows | Seagate or a purely physical surface test see this Best Free Partition Manager Freeware and free partition magic for Windows 7, Windows 8, Windows Vista and Windows XP 32 bit & 64 bit. MiniTool Free Partition Manager Software Home Edition. run it and see my pic on how to set that up. It tests the actual surface of the platters and to some extent the ability of the read / write heads.

Kishor mate a shot of your Disk Management would be good.

Start > right click Computer > left click Manage > and Computer management will come up it is a better short cut mate.
