I have purchased 16 gb pendrive from flipkart…it id not working properly.plz provide procedure for replacement
in that case you can replace it with the place of purchase so flipkart or you can contact sandisk direct for a possible replacement.
you can contact them directly through this contact details
I agree with deponia , the quickest way to replace it is to return it to where you bought it.
As for returning it to SanDisk try this link:
