I was trying to use one of hexxeh's chromium builds to install on my usb, but now I can't format it anymore. I get the error, "The disk is write protected." I've tried creating a registry key StorageDevicePolicies with WriteProtect set to 0 as suggested, and using the HP USB disk storage tool. Nothing will work.

Sadly, I don't have any computers to test it on. Also I forgot to note that it's capacity shrunk from 16gb-1gb too.

You can try Diskpart to try and wipe the USB drive and reset. Before I give you instructions, though, I want to make sure we perform the operation on the right drive.

To do this, open an elevated command prompt. Then enter the following commands and paste the output of the commands as a reply to this topic. In the command prompt type, Diskpart. When the diskpart program opens, type list volume and copy the output of the command. Then type list disk and copy the contents of that command as well.

Post the contents of both commands as a reply to this topic.

Thanks

Sorry for the delay. Were these commands executed while the USB drive was plugged in? Is the 14GB removable drive your flash drive your having issues with?

Sorry for not getting back to you sooner. To fix this problem please follow these steps:

Warning! Please read this first.
Please note, these steps will completely reformat your USB drive and you will lose all of the data stored on it.



You sound like an advanced user, but going to give detailed instructions anyway :)

Start an elevated command prompt and then run diskpart.

Use the list disk command again to confirm that we are working with the right disk. When you have determine the driver number associated with your USB drive, type select disk <number> and press enter. So if the usb drive is listed as Disk 6, you would like select disk 6.

When you press enter it should state that the disk is selected. To clear the drive, now type clean. This command will remove all partitions.

You can now type exit to get out of the diskpart utility. Now open up the Computer screen and format the USB drive.

Let me know if this allowed you to get past the write protect warning.

At this point, I would try and check it on another computer and see if the problem still exists. You can also see if there is a driver in device manager for this particular drive and try to uninstall it.

Last but not least, you should check here and see if there is a sony format utility for your drive:

Not sure if yours is a microvault drive or not.
