how can I retrieve my files in the usb?

Try the USB device on another PC. If you still cannot read it it has either failed or become corrupt and needs to be formatted.

The best way for you is to copy your files back from your backup.
If you do not have a backup, a free USB recovery tool may help you.
To tell the truth, I have never tried this freeware, but my boy friend has. His Transcend 32 GB flash drive was displayed as “RAW” could access nothing on this drive. But, his school paper that was needed urgently was there. Therefore, he finally accepted this recommended freeware to retrieve his data. God bless! He recovered all his inaccessible data back. So, you could also get your data back with the help of it.

Good luck!
