I have a 4GB HP USB flash drive that I had written a Chromium OS image to with Win32DiskImager. Now I am trying to reformat it but I can't.

Everything tells me the disk is write protected. Being a USB flash drive, there is no write-protect switch. I have tried the standard windows format thing, disk management, diskpart and HP USB Disk Storage Format Tool. I also tried the registry modification. Here is the results of trying to use diskpart: Microsoft Windows [Version 6.3.9600] (c) 2013 Microsoft Corporation.

If none of the other suggested answers here work, then your USB flash drive is probably going bad. There is a controller chip on the USB stick that manages the flash memory. If the flash controller detects any kind of unrecoverable error with the memory cells (a reallocation failure, for example), then it trips a safety condition and makes the drive read-only at the firmware level to protect your data.

Unfortunately, there is no way to get the drive out of this condition without the factory software for your drive. Flash drive manufacturers do not make this software available to the public, so the only way to get it is from Chinese hack sites. Your only option here is to replace it. The top brands (Kingston, SanDisk, Lexar, etc.) provide lifetime warranties on their products. I have no idea how to go about getting that warranty though.
