I wrote a Chromium OS image to my 4GB HP USB flash drive with Win32 Disk Imager. But now I cannot reformat my USB flash drive. It tells me that the USB flash drive is write-protected. And there is no physical switch. I have tried some methods, like disk management, diskpart, and Disk Storage Format Tool. But all of that did not work. How should I remove the HP USB flash drive from write protection? Help.
Based on your description, I can learn that your USB flash drive has been write-protected, and you cannot modify or delete any data on it. Therefore, it is impossible for you to reformat your HP USB flash drive. What you need do is to remove the write protection for your HP USB flash drive, and then you can reformat it.
Actually, some USB flash drives have write-protect switches, which are very well hidden. Therefore, you need to ensure whether it has a physical switch. If it indeed doesn't have, here are some methods for you.
Firstly, you can remove disk write protection using the registry editor.
Registry Editor can work to fix USB flash drives, SD cards, or external HDD or SSD write-protected errors.
