Since diskpart do not work properly then try regedit method.

REGEDIT

Input regedit in Windows search box, and then press enter.
(Note: May require to select "Run as administrator")

Locate the following path in Registry Editor:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

(If the StorageDevicePolicies doesn’t exist, create it manually.)

Then double click WriteProtect and set the value from 1 to 0, then press OK.

Restart your computer, and re-plug the SanDisk USB flash drive or other storage devices into your computer, check whether the issue is solved or not.
Refer to > How to Remove Write Protection from SanDisk?
And/or > How To Disable Write Protection on a USB Key

Just curious..

What sort model is the sandisk usb drive and the content inside.

Also can you read or use the content inside this sandisk usb drive or not.

While some others are unable to read and considered spoilt or damaged.

What software did you use to create this?

I've had this happen twice. Used Rufus to create the installation media. After this the drive was write protected.

I managed to recover the sandisk using methods already posted in the thread but my Lexar Jumpdrive couldn't be unlocked. Wasted.

Sandisk ultra 32gb. It's just bootable windows 10 installation media with some tools
Yes i could read & copy the content just couldn't write. All i remember was after creating the install media, i just add folder & copy over some useful utilities successfully.

few days later i decided to copy more files only to find it write protected
I have a few sandisk as well & this is the first time i have this issue

I used Mediacreation tool from microsoft to create bootable installation media. I read a few cases that this tool caused usb to be write protected

Tried Apacer USB 3.0 repair tool, works for me ...

Interesting..

For me on the bootable windows 10 installation and was highly recommended to use sandisk cruzer either blade &or orbit and either 8GB or 16GB storage only.
So far and including just now testing on one of the drive show no issue in writing folder/files into it.

Will take note on this issue on other models & higher capacity.
May try on the sandisk ultra to see if it duplicate the same.

Thanks.

Should have suggest to use 3rd party partition tools to format/delete problematic drive.

Usually i would used MiniTool Partition Magic to resolve difficult to format/delete drives that Windows tools/command unable to perform.

Windows tools/command would not be able to do anything if some forms of restrictions are in placed.


Some of the purposes of having those 8/16 GB flash drive are utilities &or tools.
Example are for bootable; MiniTool Partition Magic, Ultimate Boot CD, Ubuntu, Windows 10/7 installation, MSDOS, etc.
