1) Insert your removable media in the USB port. Notice the drive letter (say, h)
2) Open a command prompt (start>run>type 'cmd' without comma>right click on the black icon that appears> "run as administrator")
3) Type following and press enter:
attrib -h -r -s /D /S h:\*.*
So, if your drive letter is k, then the command you type will be:
attrib -h -r -s /D /S k:\*.*
4) Check your drive, you should be able to see ALL folders and files.
