What happens when you try to format it?

Lifetime warranty on Sandisk cards. I had a problem with one of my 4 year old cards earlier this year. I had to post it to Hungary I think, after filling out a form from their website. Replacement card arrived in the post a few weeks later and was a newer/faster version of the same capacity.
Cheers for reply i have contacted sandisk just got to fill out all the questions they want to know, will post here how i get on so other can view![]()
