How can I remove write protection from a USB drive?

I copied two files on my USB without any problems but got a write protection message for the third one.

Tried to create a new key and modify DWORD values in Regedit but “key” option is deselected. Typing the “cmd” command in Regedit and following the procedure is not working either.

I am using Windows XP SP2. Thanks in advance for your help.

    I think my computer has a problem because I used the same key on another computer and it worked just fine. Thanks to all of you.

    Maybe the third file you are copying is in use by another program is is locked?

      Hi Jack
      Thanks for your reply. I tried again after restarting the computer, but same problem.

    If you successfully copied two files to the USB drive there cannot be a write protection on it. Otherwise you would have gotten the message at the first file.

    Is it possible you are trying to copy a file larger then 4Gb to a FAT32 formated USB Drive? In that case you will have to reformat your USB Drive using a File System that supports larger files e.g. NTFS.

    Other possible options would be your USB Drive is out of space or the remaining space is corrupted. For the latter I also suggest to reformat the drive (don not use Quick Format)

      Dear Mike
      Thanks for your response. I did get the write protection message after successfully copying the first 2 files. The 3rd file is very small (word documents) and I have used only a small fraction of the (new) USB space so far. I tried using Regedit to "create" a new key with modified specifications but this function is deselected.
      Thanks for your help.

        It's a lame workaround but you could try opening the Word document and use Save as ... to save it directly to the USB Drive.
