Advertisements The following thread poses a question which, despite the Thread title is NOT answered as on now: Is the 6.3a Upgrade executing successfully for those who have added a second drive to their unit? (and Does it work for those who have expanded both drives as I have?) http://www.tivocommunity.com/tivo-vb/showthread.php?t=319432 I have the message saying to keep my phone line plugged in so I can receive the upgrade, but if it is going to kill my two Expanded HR10's, I want to unplug that line before the upgrade occurs on my units. As of right now it has happened on neither of my units.... Here's the key question. Do you have an HR10-250, which 1 has been expanded to a two large drive unit box (please say what you did if so) 2 that has successfully installed 6.3a and is working fine? or 3 that has installed 6.3a and is NOT working?
