Big Red X on my MyBookLIve

The power went out the other night.  When it came back on everything was working fine, but my external drive.  I have it connected to my cable modem to run on my network.  Both computers on the network have a big red X on the MyBookLive drive Z.

What do I do?

What happens when you double click it?

Hello,

Are you able to access to the User interface of the drive?

If not, try resetting the drive and then try to map the drive again.
