Write protected usb

I tried that solution provided by you to remove write protection from USB. Actually it was partially successfully! After following the procedure I was able to format the pendrive. After that I tried to copy folder of size around 5MB and it was successful but after that once again I formatted my pendrive and once again it was successful but somehow that folder was present with no files in it. I tried to delete it permanently but it was unsuccessful again showing an error code 0x80004005 in Delete dialog box. Now when I tried to copy file using tera copy it was showing error that "Specified path has not been found". Is there any hope that I can use my pendrive normally once again???
