Open it up. The rattling may be the right protect switch has come loose.
Here is a software option. There are others.
If you don’t have any important data on it just reformat. USB Drive Factory Reset Tool v3.0 is a good one.

You'll have to do the leg work. Re: partition managers newer freeware versions may not have all the full capabilities of older ones. This site archives some of the previous versions http://filehippo.com/ Look around.
ChipsetGenius will give you the flash drive chipset and firmware versions details - use an on board USB 2.0 port directly (not an external Hub).
Here is an example output from ChipsetGenius:

So you see it gives the controller brand, part number and firmware version. Cut and paste the results into a text file for reference.

Remember the firmware must be exact. You will have to search yourself. If you are not having fun here I would suggest dropping it and moving on. You have to have a curiosity with a passion to investigate this kind of stuff. If you do please keep me posted on your progress.
