I have a SanDisk USB flash drive on which have saved a lot of precious files. I use the USB flash drive nearly every day to access its information. But it has not been able to be opened since yesterday. I try to start it just now, but turn in vain. I lose those files and folders on the USB flash drive. System keeps prompting me to format the USB flash drive if I want to use it. But I don't intend to do until all data on it become accessible. What should I do? Help me, please. –Rain from Washington
