Compiling Library

I have three different hard drives that I connect to my player.  I add files to them from time to time and reconnect them back to the live player.  Lately it sits there blinking saying its compiling my library instead of saying I have x amount of files.  Now so I disconnected the hard drives and unplugged the player and plugged it back in, now its stuck on the WD TV Live screen…what did I do wrong?

You may try a reset, by holding its reset button for 3 seconds, which is located at the bottom of the unit.  If still does not boot up you may contact WD for a replacement.
