I purchased a kingston pen drive of 32 gb. On the same day I wrote some files on it. It seems to be writing and shows relevant space written and free space in its properties. But when I open a folder there are no files and folder is empty. I like to format the drive but not possible by an answer saying drive is write protected. However I can write/read another pendrive of amkette with 4 gb on the same usb port.
What is the problem? What I can do?
Thanks to all helping on this matter!:)

Once you use the registry hack, you will have to reboot for the changes to take effect. One should also note that if you are using this trick, you should make sure that the users are not administrators on the computer, because they could easily change this setting back.

This works on Windows Vista as well.
