Thank you so much! The repair tool from Apacer was the only tool in the world wide web that really worked for me in restore mode. When I tried the command prompt, it said "current read-only state: yes" but then it said, "read-only"no".

Go to "Device Manager". Select the "Properties" option from the menu that appears and click on "Policies" tab from the Properties window.

I tried every solution found over the internet including yours but none of them worked. I am from the Philippines. Thanks in advance. Be sure to select the right drive. How to Fix It. Also, check with the maker of your USB thumb drive to see if they have any tools to help, or advice to give. They may even offer a refund.

Here are some links to some major USB thumb drive makers:. Fixed it. None of the diskpart, regedit, or any other techniques worked. This link was very helpful. Find the microcontroller and download it's manufacturer reset utility. My drive's microcontroller is SMI too. The link is not working.. Do you remember what the file was called? Sorry, I need more information about your situation before I can recommend any steps. Have you tried everything in the article? Gone through the comments and tried the suggestions there? I think I've found some helpful information for you, though. It is possible that the microcontroller on the USB flash drive is corrupted.

Only re-programming the microcontroller would fix it then. I'm sorry. You haven't given me enough information to work with. Have you tried all the steps in this article? Thank you Guy for sharing your knowledge Very useful. I've done the cmd and worked for my Lexar 32 GB. I can now format it without the message "The disk is write protected". God bless you! HI Got a problem with my USB-Drive, I can't write anything in it nor format it, all this because it write-protected itself lol, since it doesn't have a write-protect switch nowhere!

Can't delete, there's no delete option on right-click! Tried formatting it through 'Safe Mode with command prompt' failed too! Tried many formatting tools and apps, some fail, some couldn't even detect it! Tried with some live cd-s fails too! There are some other suggestions throughout the comments. Check those out. It might be time to look at getting a new USB drive though.

That means that the Read Only attribute is set to NO. So you should be able to read and write to your pendrive. Thanks finally Apacer USB3. After long hours of search found this article very helpful. My drive would allow anything to be put on it. Just heaven forbid if you needed to delete or modify anything! Blasted "disk is write protected". The command line didn't work, Disk Management didn't work, and a program wouldn't work. I tried putting in my Windows 7 installation disk to use their partition manager, but that didn't work.

No more "disk is write protected" pop-ups so far and I can delete things again. Perhaps the partition table being cleared made it possible for Windows to treat it as a fresh, unpartitioned drive. I'm honestly not sure how that all worked out, but still glad for you. After I finish with the step 1 in cmd, when I tried to do formatting test I forgot to remove flash drive from my laptop before formatting and now it won't read it.

Is there any way to read it again? When you say 'it won't read it' do you mean your computer doesn't see the flash drive? Or, do you mean you don't see any files on the flash drive? If you can see your flash drive in Windows Explorer, but you don't see any files on it, that's because the formatting erases everything on the flash drive. If you have the flash drive inserted, but you can't see it in Windows, I recommend trying the different software utilities like the Apacer and Kingston tools.

Now if I can just convince Apacer to give me a dollar every time I send someone their way. Apacer worked like a charm on my Corsair voyager slider 64G, instead of formatting, I picked restore and it worked!

Got rid of write protect and back in business. Just wanted to drop a line to show my appreciation. Oh, wait, the Apacer utility worked once I did the restore first instead of format.

It was also not write protected after the restore. No format necessary! Unfortunately, neither utility worked for me on the same Kingston drive in the article.
