Before a couple days ago, I hadn't cracked open my Tivo in 5 years, and little things like "jumpers" had completely slipped my mind.
The right answer, was, of course, to check the jumpers. Tivo works as expected, with double capacity.
Thanks for the clue.
However, if both of those drives were Seagate model # ST3160815A, then you could juggle jumpers 'til you were blue in the face and no combination would ever have worked.
You could use one of them by itself or in either position with almost any other drive, no problem, but together, nothing but fail.
And Series 1s don't like Caviar Blues for some reason either.
None of the above applies to S2s.
And don't forget, when using a SATA drive or drives in an S1, the adapter has to be Marvell chipset based.
