I have a pair of 3TB Bolt+ units (long story). One is in normal use and one is emergency spare. The main unit failed and I will be ordering an external 3TB Tivo-formatted drive from Weakknees. I want that unit to return to being the primary unit so that the stupid 2.5" HDD in the backup unit lives to record another day. In the meantime, that unit has amassed a bunch of content - content which I wish to transfer to the primary/WeakkneesHDD unit. Because I only normally run one Bolt+ at a time, I only have one cable card from Cox. Will I need a second cable card to do the data xfer OR is there a better way to move the data from the backup unit's 2.5" HDD to the new 3.5" external HDD? Both are 3TB but that's likely the only similarity. I realize that some of the data won't (or at least shouldn't) move due to copyrights, etc, hence my "is there a better way" question.
