Claiming waranty for Hard Disk brought on Flipkart

Generally the invoice is your warranty. When things go wrong, you just show them the invoice. Don't know if WD has some special norms or not.

In most cases invoice is also not required. By feeding the serial number, the service centre staff gets the details of warranty and either repair on the spot or courier a new one at the registered address 

For WD, register the product on their website after uploading invoice copy to confirm how much actual warranty you are getting. Sometimes the difference between mfg date & invoice date is large so warranty by default starts from mfg date & after uploading the invoice one can raise a complaint to WD support to start the warranty from purchase date. Once that is done you only need to take the hdd to WD service centre in future & based on its serial number stored in WD database they will provide warranty.

don't forget to verify disk storage using any disk checking softwares, if you locate bad sectors or storage errors return it right away without hesitation, high chances of counterfeit or used product sold to you.

I claimed warranty for WD external hdd that bought from Amazon by downloading the invoice and then directly gone to the service center and they will replace with a refurbished hdd
