And if the main suggestion, going to Device Manager and optimizing performance, and the HP USB FORMAT TOOL does not work?...
just click start then hover the mouse to computer or my computer then right click select manage then select disk management. from there you should see the flash drive that you wanted to format it should be labeled as unallocated size/disk. then just right click on it there's no other option just click on add new volume then the rest go on. hope this helps.
it does not as well nstill cannot complete format

First, connect your USB device to your computer. Then right-click on My Computer from the desktop and choose Manage.

manage my computer

Next click on Device Manager and then expand out Disk Drives. You should see your USB drive listed there as "Generic USB 2.0 USB Drive" or something similar.

usb disk drive

Now right-click on the USB drive under Disk Drives and choose Properties. Then go to the Policies tab.

optimize for performance

Now you will see two options, the "Optimize for quick removal" selected by default. Go ahead and change that by selecting the "Optimize for performance" option. This enables writing caching on the drive and therefore allows you to format it as NTFS! Sweet.

That's it. Now click OK and then go to My Computer. Right click on the drive in My Computer and choose Format. In the File System drop down you will now see the option for NTFS!
