Firmware or HDD issue?

Folks are trying to help here and that’s great, but the ball has been dropped.  Are you using the rear USB port or the front one on the device?

It is a fact that the rear port does not work correctly and WD can’t fix it by any practical means.  The web and this forum is littered with incidents related to the “rear port problem.”  Here is one thread:

If you are attempting to use the rear port, it may work for a while but you will definitely encounter freezes, errant ejects, multi hour file transfers, etc.  This problem has been reported tons of times over the last year.  The problem is big enough to make some new users return multiple devices and then conclude that the thing is just junk and doesn’t work.   WD obviously knows this and if they could fix it they would.

I like the WDTVLSMP but I never count on that rear port so I’m only mildly irritated.
