Edge 16gb stopped working

Hi there , i got this pen drive at the start of the year and it was working great … but suddenly stopped working back in August.Ive tried to format unsucessfully .

 I did register it back when purchased and reported it when it stopped working. I have found the online reservation for the item but don’t have a proof of purchase or serial number as requested by the support team…

Can anyone help me …

Many thanks


If you registered it with SanDisk online when you bought it as you say, then they already have the serial number and there should be no issue in claiming warranty replacement for it.

This was the reply i got when I contacted Sandisk…

I recommend skipping directly to the Replacement steps.
