I suggest two steps to start. DO NOT format the drive.
1) See if it works on another machine. If it does, use that machine to save the data.
2) If you are handy with tools, and have access to a desktop computer, remove the drive from the USB case and attach it directly to the motherboard controller port (and power). If the problem was with the USB part, your data will be there, fat and happy.
4) If none of the above work, we have to look at tools that do sector-by-sector scans of the drive to recover whatever data can be salvaged.
Do you have backups? If not, go get a backup device and make copies of everything that you still have that you would not want to lose. Backups are a lifesaver when a drive crashes with data that you need.
