I have a 4 tuner tablo and a WD 1 TB passport ultra that I have been using without problem for about ten months now.
About a week ago I started occasionally having some pixelation issues with some random channels. Sometimes pixelation on one channel but not the other, sometimes the other but not the first.
After doing a bunch of other things which had no effect on the issue, I discovered that if I disconnect my hard drive I get a clear signal on all channels. Reconnect the hard drive and random channel pixelation occurs.
I saw a couple of threads where a question was asked about disconnecting the hard drive and checking the results, but those threads didn't have any further information about the issue.
Is anyone familiar with this issue? Is it possible to get back to normal functioning if I reformat my hard drive? Does it sound like I need a new hard drive? Are there other matters at play that I need to look into?
