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"?

there is no data to recover and I tried both tools neither one worked

no they just did not work

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:

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

Device Type: Mass Storage Device

Protocal Version: USB 2.10 <- Hint: This device can run faster when plugged to a USB3.0 port (Note - would NOT work from my USB 3.1 ports)

Current Speed: High Speed

Max Current: 300mA

USB Device ID: VID = 1005 PID = B128

Serial Number: 0703677A1B7B1768

Device Vendor: USB3.0

Device Name: FLASH DRIVE

Device Revision: 0100

Manufacturer: USB3.0

Product Model: FLASH DRIVE

Product Revision: PMAP

Controller Vendor: Phison

Controller Part-Number: PS2251-07(PS2307) - F/W 05.01.10 [2016-03-16]

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.

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.
