The poster discussing the issues about how to incorporate combining the internal and external together makes an excellent point. Using current technology, it seems the only way for this to work is when you hook up the external drive, it would have to wipe out all material on both drives to create an LVM, so you couldnt just fill an external drive, and hook up another one on the fly, it would have to completely wipe out the data on the internal drive again everytime you decided to mate it with a different external.
I raised this problem on the "esata but..." thread a while back.
I need/want the 2 drives to work together--but not if it's going to reformat the esata drive.
My greatest fear (OK, a little hyperbole here) is that a CE will activate both drives, and my recordings will vanish. On one DVR, I filled up the internal drive (granted, with stuff I may never watch) before adding the external. So that would be a potential TB of recordings vanished. And if we're given a warning (this new software will wipe out your external drive), we need (not want) to have an option for playing those recordings, such as an option that will allow us to continue to use the drives separately until they can be safely integrated.
Earl keeps telling us that the esata support is a lower priority. Until DTV can find a way to allow us to continue to use the recordings on our current external drive, I'm willing to wait.
