Unable to format Dell USB

Hi Aithusa27,

We strongly recommend you keep that USB key in the event that you ever need to replace the hard drive. 

Listen, I really need assistance with this. I have the same media stick. I have the pop up asking me to update my backup and restore. No problem. I want to UPDATE it on THIS stick because it's large enough for it, unlike other USB drives that I have. Is there any way that you know of to be able to write to this disk? As it is now, because of the update, this content is no longer the latest anyway.

So do you know how to do that? Or not? Thank you in advance.

Hi, i have a question, i have a Black and a Silver Stick. On the Black Stick its no Problem to unlock, but on the Silver Stick the unlock isnt possible. Can you Help `?

No on an idea ?

I have a Dell Media Mentor USB restore media for Dell 14Z 5423 ultrabook. The Dell Restore media is giving me autorun.dll error and I want to know if I can fix it by copying a fresh autorun.dll to the USB. I have not done any change to official media so it seems only one dll is corrupt. Any guidance will be helpful

Awesome, procedure 2 worked for me even though I didn't had blue label USB stick. Thanks a lot.

The procedures mentioned above didn't work on the latest sticks, but the following did like a charm. absolutely brilliant.

As for removing write protection from USB, you can try the following methods:

1. Check the write protection switch if available

Some USB flash drives have a physical switch which allows you to lock or unlock write protection. The location of a switch on a USB flash drive will be different. Make sure the lock switch is slid up to unlock position. 

2. Clear read-only attributes with DiskPart utility

2.1. Press Windows key + R combination on your keyboard. In the pop-up Run dialog box, type diskpart and hit Enter or click "OK" to open the DiskPart Command Prompt.

2.2. Type the following commands one by one and hit Enter after each:

list disk - all of the disks connected to the computer will be displayed, including internal hard drives.

select disk n - where n is the number of USB flash drive. You can use the Size column to identify which one it is.

attributes disk clear readonly - change your USB's properties so that it is no longer read-only.

2.3. Close DiskPart Command Prompt and re-plug your USB flash drive to check if the write protection error is resolved. 

3. format the usb

If you've tried all steps above and still can't remove the write protection from USB drive, you may need to format the USB. The problem is how to format a write-protection USB? You can do this via a professional disk formatting tool. It can directly format it even when the USB is write protected. Much easier and simpler than other methods.
