“Once connected, all recordings automatically record on your eSATA device until it is full or disconnected from the DVR. Once your eSATA device has reached recording capacity, additional programs then record to the hard drive of your DVR.”
This new feature would make it possible for the customer to permanently remove the external drive, once its content has been viewed and/or deleted. Otherwise, the customer is not only stuck with content on the external drive, but also the inability to prevent additional scheduled or manually selected recordings from being added to the external drive while the customer is trying to "catch up" with unviewed recordings.
2. New setting allowing the user to specify whether the external or internal drive is used for "caching" the currently selected station (tuner channel).
This new feature would alleviate the need for constant disk access of the external drive, when not set as the "cache."
3. New setting allowing the user to specify whether a specific program or series is to be recorded on the internal or external drive.
4. New ability for the user to move content between external and internal drives.
