Unable to copy data WD 1TB USB Drive

I have one problem regarding my Western Digital Elements 1TB Portable External Hard Drive (Black)
Product URL on Amazon :

Problem :
Sometimes it’s get detected sometimes not(10 out of 2 or 3 times only get connected)
It shows the folders on drive but if I try to copy the folders data it stop responding.

How can i copy the data from drive to my PC.

Hi pravin.kakde003,

Are you getting same issue when you connect WD Element drive with other computer?

I would recommend to run Drive Test using Data Lifeguard Diagnostic Tool to check the health of drive. if drive passed, try to connect drive with another computer and copy the required data from the drive.

I tried to connect with other computer but same problem persist.
Check with “Drive Test using Data Lifeguard Diagnostic Tool”, It failed to test.
