Maybe yes, maybe no.

 

It is possible that the stick became "bricked" because of an "extraordinary case" or because it developed some hardware problem.

 

In any case, you will lose any data currently on it, so, if you have still read access to the data, you should make a copy/backup of them before anything else.

 

The next problem will be (if available at all) a suitable tool.

 

Unlike more "common" manufacturers, I don't think that SANDISK "MP tools" (or similar) are available.

 

USBDEV.RU, which normally hosts all (or nearly all) available tools seems to only have a few "U3" related tools for SANDISK sticks:

http://www.usbdev.ru/files/sandisk/

 

If you have any chance of a replacement under warranty you should try that route first, 

http://kb.sandisk.co...n-(rma)-process

 

It seems, judging from this:

that your reported issue is rather common :(, but seemingly no solution has been found for it.
