Bought a brand new WDTV live and updated to current firmaware. Bought a 3TB WD My Book, kept default formatting, copied over a a folder of movies. Plugged in the drive to the Live but it says no dirves attached. Have no idea what the problem is.
Did you safely eject it from your PC before you unplugged it?
I am having the same problem with my WD TV and my WD BAAU0030 3TB USB drive. The WD TV will work with smaller drives.
I have a feeling it may be the 3TB drive.
The thing it’s supposed to support the 3 TB drive.
