I appear to be running Passport software and Time Warner is my cable provider in the Raleigh, NC area. (The boot up screen says Mystro, is that a TWC OEM of Passport?)

This is a new unit I got from TWC and I wanted to upgrade the capacity. So I checked with Weaknees and they said that they've had multiple successful reports of their Scientific Atlanta upgrade working in my area.

I didn't have instructions to follow so I pulled the power on the 8240 and connected the drive. It was definitely recognized because once the unit started up the DVR prompted me to format the drive. Unfortunately, after approving the format I didn't have any increase in available space. (Assuming my percentage is accurate.)

Shutting off the external drive does nothing. Restarting the external drive causes the DVR to pause for a few seconds, although it then resumes with no further messages.

Any ideas? Any ideas on how to get into a diagnostic menu? Google seemed to indicate holding the select button until a letter icon appears and then the info button. Which almost worked: I get the letter icon, but no menu after pressing info.

I hate to give up on this because the port is clearly active. But I'm at a loss for what to do next.

Thanks for any tips,

David
