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.
More. . .
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:
"Description: [I:]USB Mass Storage Device(USB3.0 FLASH DRIVE)

USB Device ID: VID = 1005 PID = B128
Serial Number: 0703677A1B7B1768

Flash ID code: 983A94937651 - Toshiba [MLC]
Tools on web: http://dl.mydigit.net/special/up/phison.... " Mainly in Chinese but utility names are in English so cut and paste and do google search.
So you see it gives the controller brand, part number and firmware version. Cut and paste the results into a text file for reference.
This is a good site.

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.

how do I take it apart?
Hi John,
Just GENTLY pry it apart using your finger nail, a small artist spatuala, etc. Most important take your time and enjoy figuring it out.
If you don’t have any important data on it just reformat. USB Drive Factory Reset Tool v3.0 is a good one.
I've been very busy lately so I will do this later probably in a week or 2 I will keep you updated

I have the same problem. Same, it is a Sandisk Cruzer USB. It happened suddenly, 1 day I decided to format and hope , enable to write, or write protected.
During my research peoples, I read that it happen after using something like secure vault, or dont know what. but I never used that $@$* secure vault or dont know what provided by Sandisk.
Another reseach told me that those Cruzer USB are faulty and should be sended back, they gona provide another one.
Except warranty is gone + in my country no warranty disponible or Sandisk store.
I tried everything, even GParted through DOS. Nothing works!!
Never ever buy again a Sandisk or Cruzer product!! Luckily there is no data on it.
My best guess, internal software need to be flashed back, with something through DOS, not through Windows, cause Windows is very poor for managing other devices than itself. Maybe by Linux. Unfortunatly I could not find anything over the net for this problem, most people say it is locked by the small Switch present on the USB, except there is no switch!

I know this is over A year old but if you want what seems to be the best drive software that fixes everything from flash drives to floppy drives, hard drives to solid state drives check out spinrite from steve over at gibson research. Here is the link. https://www.grc.com/spinrite.htm

Hi John,
You didn't answer the question "Is there data you need to recover?".
If not use "USB Drive Factory Reset Tool v3.0"
https://usb-drive-factory-reset-tool.upd...
Did you run the freeware "EaseUS CleanGenius"?
https://www.easeus.com/storage-media-rec...
