help!!!Can you give more INFORMATION about this please? The make and name of the PRODUCT. That way we could look up some information to help you with. Also has it worked fine before? Is this SOMETHING that started happening after you did something with the device? Things of that nature will help us FIND a solution for you.

In the meantime I would like to refer you here. This is their website and the contact tech support section. I hope that helps you out a little bit.USB flash memory stick. Check if the write protect switch has been moved.

no switch for this flash drive...
before it became write protected, it happends to"hung" when half way traffering files. and caused my pc hung too, then i do pc reset(power button).
after reboot,i try to format it, then the error message appeared.

visit Transcend`s online download center at http://www.transcendusa.com/Support/DLCenter/index.asp; enter the part number (e.g.: TSXXJF110) to search for the corresponding JetFlash drive’s download page. Please download the "Recovery Tool" software; install and then run it to restore your flash drive.
