I have the DCH6416 DVR. My cable co is Time Warner. I checked the status and all my ports (USB/FireWire/eSATA/Ethernet) are enabled. I tried hooking up an external FireWire/USB 2.0 120GB drive to the box and it recognizes the drive, but I can't figure out how to get the DVR to use it.
The way I checked is powering down the box and hitting OK which takes me to a dignostic menu. It shows in realtime what devices are connected, so when I turned on the HD, I could see it pop up on the screen when using either the FireWire or USB ports. The regular DVR menu (box powered on) did not list it however.
I guess my main question is do you need the cable co to install software in order to use an external HD? Or is having the ports enabled and the HD recognized enough?
BTW - I am just looking to increase storage, not to transfer the files. Also my firmware version is 18.20 and my SW vers is 74.53-3321 if that helps.
