Hi there knilesh,

You should go to Disk Management and see whether the drive has healthy partitions and file system. If not, you may need to use some data recovery software.
Also, you can test the drive with WD's DLG tool. If the drive fails one of the tests(extended and/or short one), you can contact WD's Support either by phone or by e-mail and eventually RMA the drive.
