This seems to be the problem of most of us these days and some of our readers who wanted to know the methods how they can remove the Write Protected error from their USB drives like Pen Drives and memory cards.

What is Write Protected error and why it happens?
In the Write Protected error, we can’t write or copy any data in our flash drives and even can’t format the drive.
There are many reasons that cause this problem, let’s see solutions of them.
•    First of all try to locate a small switch (if any, that you may have not noticed) at some place on the drive or memory card reader. This is the prime reason for this error. If there is one, switch it to the other side to turn the protection off.
•    Yes I know this problem is also occurring these days without this switch but not to worry. Just download this helpful software from here and run it to execute a “low-level format” on the drive. This software is quite handy and may take few attempts to actually remove the error.
If that low level format tool does not work, try another one Link.
•    The problem can also be caused by some virus activity so just get it scanned by some updated good anti virus which may solve your problem.
•    BUT if none of the methods listed above solves your problem then your pen drive might have gone corrupted, so just get it replaced.
Hope any of the methods listed above solves your problem.
Update 1:
After the low level format, you may need to “Partition the drive“. Dont worry, partitioning a pen drive means allocating it its File System and Cluster Size that was lost after the Low Level Format.
For that:
  1. Run diskmgmt.msc in Run.
  2. In the disk management window, select the pen drive, right click on it and click on Format.
  3. Now choose the File System and Allocation Unit Size and do not check the boxes below.

Click OK and the drive will be reusable after this.

Update 3 (Solution Working):
Thanks to one of our readers Jim, who let us know about the tool called Neo 9, using which we can easily this write protection problem.
For transcend drive users, try the tool at this link, it has been found to work.

  2. Hey Curt, get a real life you bottom feeder!

    Why do you feel the need to be a low life?

    The information you provided is crap and worthless, hope it pays well!

  3. Hey, there's some dangerous advice here - and it's a bit all over the place. Be especially careful trying out the Neo9 - it appears you have to put it on the drive itself, luckily it had the sense not to format drive C...

  4. So my USB drive is in G, but i have to format D drive in order to partitioning, right? or not? because when I right-clicked G drive, the format option is freeze. sure it won't delete all my D's data? thanks before for your help

    1. Please be clear with your question... or else you won't get a clear answer.. its pretty hard to understand what you're trying to ask.....


  6. "For transcend drive users, try the tool at this link, it has been found to work."
    i don't know why, my FD can't be access anymore after i used this trick. my transcend FD death now...

  7. Neo9 worked great.
    I ran it on my desktop. It formatted my USB Flash in FAT32 and broke the write protection.
    I had been trying to do that for weeks, everything failed.
    Neo9 saved me.
    Some programmers rock!!!
