Hello.

I have bought sandisk pan drive 12 month ago..
Now suddenly it's get corrupted and stop working. When i report a problem in sandisk customer r care and describe all the problem.. And the informed us that product is an authentic. It's realy dissapointing.
I have attached a screen shot of email forwarded by sandisk.
I have also attached the bill of purchase..
