A lot of people would hate that, but isn't it just speculation that a new storage scheme would require reformatting the drives to allow both the internal and external to work in conjunction?
I'd hate for them to suddenly put out firmware that allows usage of both that would have to format my externals to allow this new "feature" to work.
We don't know how they're going to do it, or when, but how great would it be if they put out firmware that allows usage of both drives that does not require a reformat of either drive? If you've been using an external drive, the worst that would happen is you'd see any programs recorded on the internal drive. That would be the best scenario...
I'm convinced that use of eSATA drives one day will become a supported feature, so I just hope DIRECTV doesn't go a proprietary route and require we buy a drive and enclosure from THEM.
