Re: i want to remove 16GB kingston pan drive write protection
Does your pen drive have a write protection switch on it anywhere? If it does, move it across and try again. Try booting your computer in Safe Mode and try to format it - to boot in Safe Mode, tap F8 until you are taken to a new screen with a list of options.
If neither of these work, try opening a command prompt by going to Start > Run > Type "cmd" and press enter. On the new screen that opens type "Format X:" - replace X with the drive letter of the pen drive.
