Windows 7 – Formatting PNY USB Drive that is “write protected”

Please do not mark my question as a duplicate, as I have read the solutions to many of the same questions and despite applying them, I still have the same problem.

I have a PNY 64GB USB drive, but I cannot delete files from it or add new files to it because it is "write protected". I am using Windows 7.

What I have tried:

1. Locating a switch, there is none.

2. Trying to find a "Security" tab when in the properties menu of my USB drive. There isn't one.

3. Trying to format it outright by right-clicking my USB Drive in the C: folder, and going to "format". It fails and tells me that the file is write protected.

4. Using "Filepart" from the Command Prompt, selecting the right volume, and changing the attribute of the readonly option. Still tells me that the disk is write protected when I try to format it.

5. Inserting the following code into a .bat file and executing it (as was suggested by a user on StackExchange to a similar question):

   reg add "HKLM\System\CurrentControlSet\Control\StorageDevicePolicies" /t Reg_dword /v WriteProtect /f /d 0

6. Trying to edit my registry directly. The problem with this approach is that I am missing the folder required, "StorageDevicePolicies". So I created that "key" and put a DWORD value called "WriteProtect" in it, with its value data set to 0. Still the USB Drive is "write protected".

7. Attempting to format through diskmgmt.msc, again, same problem: tells me that the file is disk protected.

8. Downloading the HPUSBDisk-2.2.3.exe, which was supposed to be able to format my USB Drive but resulted in the same thing–cannot format because disk is write protected.
