I have been trying to free up some space on my H3 hard drive, but I encounter errors a lot. If I choose more than 2 recordings at a time to transfer, It will say that I unplugged a USB device and stop the transfer. When I hit DVR, my EHD is no longer listed. It will show back up a few hours later or if I unplug and replug the EHD. If I move 1-2 recordings at a time, it works fine. Anyone else seen this? The EHD is an older USB 2.0 Calvary drive that I have used on my Hopper and Hopper w/ Sling in the past.
