Format write-protected USB drive
« on: October 08, 2012, 12:53:24 PM »
I'm trying to format my USB drive, but every time I try I get the error "This media is write protected" I tried some programs but they all try to "just" format the USB and gives me the same error. I have created and set the StorageDevicePolicies in registry to 0, and tried to delete it with Unlocker. The USB have two partitions, one that acts like a normal USB, and the second that is write-protected and  have auto start with some .html files in it. And it's the second partition that I want to remove, I don't care if I have to remove everything from the USB.

Seen this before on promotional drives given out at events. Are you trying to wipe one of these drives clean to use as a personal thumb drive? If so i haven't found a means yet to wipe them to use them as free bee pen drives. I have heard "rumor" that companies that have these mass produced use either a single write flash chip or laser cut an open into the trace for "writing" making them read only.

Yea, I got it from school and it's quite annoying because it's auto run every time. But I guess it's nothing I can do then. Thanks anyway.

As Dave states, most Memory Chips used in flash drives have a facility for write protection. Mot flash drives nowadays usually just leave this circuit closed, allowing writes. Back when they were fresh and new, though, Flash drives had a write-protect switch controlling that trace.

The existence of said switch notwithstanding, though, you don't have many options outside attempting to complete that trace yourself somehow.
