Hi vikas78,

I am sorry to hear about it. Based on the Data Lifeguard Diagnostic utility test result, it’s a hardware issue and If HDD is still under warranty, I’d suggest you to proceed for an RMA. For RMA service, you may refer to the link below.

For data recovery, you can try the data recover software’s. If the data is very important and you want to recover it, there is possibility to cover by data recovery companies.

Good Luck.
