Cruzer micro

Help! I have a cruzer micro that was working fine then plugged it in and it won’t open. Shows up in my computer but a message comes up " the semaphore timeout period has expired." . Is there anything I can do to recover my files? Thanks

A strange error Patty.  If you can’t Safely Remove the drive shut down the pc then remove it.  Then try it in a couple of different pcs, preferably with different OSs even.
