Advertisements I have replaced the internal drive on my Tivo Series 3 with a 1TB replacement drive. The new drive seems to be working fine. Before this I had a 500GB Western Digital external drive attached. Before upgrading the internal drive, I removed all program information from the system and divorced Tivo from the external drive. Now, Tivo recognizes the external drive (the serial number appears in settings) but I keep getting an error message: Tivo has detected that an external storage device is attached. You need to set up the device to increase the recording capacity of your DVR. I click "yes" and the system reboots but then I get the same message that the external device needs to be set up. (If select "skip," I keep getting the same message.) From looking at earlier postings, with a total of 1TB + 500GB, I should be able to use both the internal and external drives. Is there anything I can do to get the external drive "married" to the system with my new internal drive?
