"Hi! I have a SanDisk USB flash drive of 32GB capacity. Last night when I inserted it to my PC, it cannot be recognized as a removable device as usual. Instead, I could find no information about the USB flash drive on My Computer. Under Disk Management, the USB flash drive showed as an unformatted drive. Windows asks me to format the disk drive when I double click the USB flash drive. I cannot read any data from the USB flash drive though it contains more than 1000 pictures and some other files. How can I fix the unreadable USB flash drive and get back all lost data?"
