I've been stuck with this question for a while and never found a solution. My USB has a password protection feature on it and I think it stops it from being bootable.

Locked:

usb locked

Unlocked:

usb unlocked

Does anyone know a way to remove this feature and make it bootable? Perhaps reflashing the usb stick?

Thank you in advance.

EDIT

It seems to follow this standard: IEEE1667

I found this chinese(?) page with some low level tools which I can try: http://dl.mydigit.net/special/up/phison.html

Can you give any details on the pendrive's model or at least manufacturer? – gronostaj May 21 '13 at 10:48
    
@gronostaj I believe the brand name is silicon power. – Rick Kuipers May 21 '13 at 11:21
    
@gronostaj The model is D33B29 I think it's also known as Helios 101 – Rick Kuipers May 21 '13 at 13:07

I think if you format your USB drive it will lose all settings including password ones.

Worth a shot, I'll repartition it, see if that works :-) – Rick Kuipers May 21 '13 at 11:22
    
Obviously, do a backup before repartitioning ;) – Andrea Gottardi May 21 '13 at 11:26
    
That's what I'm doing at this very moment :-) thanks for the notice though. – Rick Kuipers May 21 '13 at 11:27
    
It didn't make a difference, tried everything with the partitions using EaseUS Partition Manager but the whole password feature isn't on the partitions. It doesn't show up as a disk if I don't unlock it by entering my password first. – Rick Kuipers May 21 '13 at 13:36
    
But you formatted only a partition or the entire disk? – Andrea Gottardi May 21 '13 at 13:38

Note Try using the UFD Recover Tool I mention at the end of my post FIRST, maybe just that is enough, I didn't find it until my last couple of steps.

I ended up using ChipGenius to find my VID and PID. I filled those two in on flashboot.ru and found out which controller I was dealing with. It was a Phison, then I googled and downloaded Phison MPALL v3.29.0B and with a combination of using this guide and a lot of trouble shooting I finally got it to disable IEEE 1667 (mode 3).

In the end I ended up having a "Super Floppy". Then I finished off using this UFD Recover Tool. And now I have a USB with MBR, without IEEE 1667 (password) and perfectly bootable.
