I have a USB drive that I can't delete anything from it or write to it. I can't format it as well. Any action I am trying to do, an error will pop up and say "This disk is write protected".

I tried to fix it with diskpart by clearing the attributes from the disk, no luck.
There's no physical switch on the USB drive.

 

Do you have any suggestions how to remove this annoying write protection?

This can happen for two reasons, 

 

The USB is counterfeit in that the flash drive has an advertised large capacity and it's very inexpensive. Once the data is attempted to written past the real limit the drive because write protected.

 

The USB drive detects a hardware fault and becomes write protected. If this only happens to this one drive there is nothing that can be done other than possibly flashing the firmware if one it even available.

Have you tried a Linux based distro such as Hirens or Dban that run from the DVD drive?  Just be super-careful not to accidentally nuke your main C:\\ drive. Maybe unplug other drives and leave only the flash drive plugged in. Or maybe Aomei Partition editor which you can install on your main HDD.
