External harddrive not seen after update

I have a WDTV live and I use a WD passport external 1.5 T to hold the content. Everything work fine until there was a update this last friday"3-8-2013" and saturday I added some more content to the passport that pushed it a little over 1 T. And now the WDTV just sayes “connecting to usb …” and usually thats on for maybe a minute if that. But now it was on over night and still nothing… Is that to much content or did I get a bad firmware update?
