Just made the jump from the R15 to HR20. I have read a lot of posts about esata and I would like to know if any one has disconnected the internal drive and run on esata only. I am aware of the "breaking the seal" voids warranty stuff but I know my around computers and unhooking a HDD is no big deal. There has been many posts about heat problems and shutting down the internal HDD would sure cool off the box plus you would not wearout the existing drive doing nothing. OR does esata shut down the internal drive ?
