I recently switched from DTV, I have a 922 in my living room now. I want to repurpose my EHD so I switched the lead from an eSata to a USB and plugged it into the back of the 922. Nothing. No message to inform me it needs reformatting, no flashing light showing disk usage, nothing. I plugged it out and in etc. Nothing. The drive worked fine on my DTV HR20 unit, but nothing on 922. Any thoughts?
