one thing is u should make sure it is charged
then one thing that worked for me previously is have it turned off and connect it to USB port on windows.
it should show up as a usb drive.
format the drive with FAT (=FAT16) and DO NOT have any "disk name" (not even "no name" as under MAC. disconnect the drive with eject device after closing the file mgr on that drive
restart should hopefully then bring up the empty reader. it only works however, if it does still show up as a usb drive. and afterwards u may want to use the option "format" under tools.
