The flash drive was already kind of broken when I was using it. When plugged in, it would periodically disconnect from the computer. Then one time, a pop-up said I needed to format the flash drive in order to use it. I brought it to someone who formatted it and then used some recovery program to retrieve the files. He got about 80% of the files back, but only about 25% of them can be opened. The rest give an error message.
Anything else I can do?
