write protected..!!!???

HI, are you using this in a Mac or Windows? casue it might not be formatted in the correct format for Mac. It should be Formatted in Fat32

Some USB flash drives have a mechanical switch on them that puts them into Write Protect mode.  This can be a very small slider switch which may have caught on something in your pocket or computer case. If this is the situation, then simply move the switch to the unlocked position and try to copy files again. It should work now.

If there is no switch, Check the File or program you are trying to copy. Right-click on the file that you’re trying to write to and then click on Properties. Now you’ll see some options at the bottom of this window and one of them is Read-only. Make sure this box is unchecked and then click on the Apply button. You should now be able to write to this file.

There is also a Registry fix we can try, but you MUST first BACK UP, your current Registry.I will explain later if the above don’t work.
