Back in 2011 I bought an external WD 500GB powered HDD for the 211k. It seems to be getting a bit glitchy so a while back I bought a Toshiba 1tb portable drive with a powered hub as I could not find a 1tb regular powered drive here. Anyway I got the 1tb hooked up and got the 211k to reformat the drive. So I decided to see if I could get a bit more mileage off the old WD500GB for a while. Today, I decided to hook the 1tb portable HDD back up through the powered hub. Well, after I turn off the 211k, hook up the 1tb, I turn it on, it will not do anything. The receiver seems dead, no message, no nothing. I tried several times, trying different hub connections, in case one did not work right. I finally decided to hook the old WD500 GB one back up and everything is back to normal. Any idea what is going on? Thanks.
