    As for connecting it all you have to do is do a menu restart and when the lights go off on the front of the unit pull the power cord. That is the safest way to do it. Then connect the eSATA cable to the external drive and the HR21. Then plug the eSATA drive in and let it start up. Then plug the power cord to the HR21 in and it will start up and be ready to go.

    Leave something recorded on the internal drive so when you boot up with the eSATA drive you can make sure your "My Playlist" is empty so you know it is working correctly.

    As for drives that work I don't know. I do know the WD My Books do not work on DVR's and the Seagate Free Agent Pro's do not work on the HR21's.

    Thanks. Which hard drive is good for the HR21?

    Why would you think that would be any safer than simply leaving both power and eSATA cable connected, and simply pushing RBR followed by the power button on the external drive to move to the internal, or pushing the button on the ex drive, waiting 15 secs, and then RBR on the DVR to move to the ex drive? I've done it that way about 20 times now, and never felt like I was placing anything at risk.

    I have not personally connected one yet but I believe the proper way of doing it is to have the unit unplugged like I said above but I am sure the way you said will work too.

    But one thing you are definitely doing the wrong way and you will damage the internal drive at some point is pressing the RBR. Doing an RBR or pulling the power cord when the unit is powered on is the last thing you want to do. You always want to do a menu restart when possible.

    DVR's are like PC's and it is never good for the hard drive to crash to do a power lose. Doing a menu restart shuts the unit down in order just like a PC does.

    Just like Rick in Casablanca, you may be misinformed.

    And, BTW, that's exactly why I don't pull the power cord.

    The first thing a drive does when it loses power is that the actuator stops moving, data stops flowing, and the platters stop spinning. That's it. None of that is going to do anything to skunk the drive or the data on it. The OS could care less, as it gets everything it needs during the subsequent boot, where it also looks for a boot up drive, defaulting to the ex drive should it be available, and to the internal should it not. Obviously you don't want to do any of that in the middle of a live recording, which you would lose, but a buffer recording is not that precious, and you will lose that anyway.

    A "menu" restart is no different than a RBR restart. Both do exactly the same thing, which is suspend everything else and reboot. The biggest difference is you don't have to get off your fat ass to do it with the remote, but since the remote doesn't work for the ex drive, a little exercise is in order anyway.

    This is Unix. There is no Windows NT-like behavior where housekeeping must be done and stuff needs to be writtten to the drive first. It just says "OK, you're done recording and want to reboot? Here we go!"

    But if superstitious behavior makes you feel better, vaya con dios.

    Menu restart does a shutdown.. RBR is the same as pulling the plug..

    Powering down the HR2x should only be done as a last resort if you are having trouble getting the DVR to recognize the external drive.

    Just plug in the external drive (power and eSATA cable connection) and do a menu reset on the DVR. Once you have confirmed that works, to switch between the internal and external drives, power the external on or off and menu reset the DVR.

    Menu restart does a shut down and an immediate restart (which is why the term "restart" is smack-dab in the middle of the name).

    Pulling the power plug shuts the unit down, putting it back in does a restart.

    Pushing RBR may be equivalent to pulling the plug and quickly plugging it back in (as far as the OS is concerned), but why would you think there is anything different about either of those than there is about doing a menu restart, which really does the exact same thing?

    That is unless you attribute some sort of voodoo or magic power to the "shut down" procedure, which is no different than it would be if your power went out. Again, there is no housekeeping before shut down. It aborts whatever it is recording, and restarts as soon as it sees power, no matter how you approach it.

    A shut down is a shut down, and a boot is a boot.

    Pulling the power cord is probably the last thing you want to do, not because it shuts down differently or boots up differently, but because electronic equipment generally lasts longer if you don't power cycle it very often. I would reserve that for problems not fixed by a restart, or if you wanted to move the unit. Only.

    IF you were going to go to the bother of disconnecting and reconnecting eSATA connectors (which I don't recommend, as they are not designed for constant use) it might make sense to also disconnect the power to the PVR and drive. But since none of that is necessary, it really doesn't matter.

    Am I to understand that you cannot access both the internal and an external drive at the same time?

    Is there a FAQ regarding all this for the HR21-700?

    Take a look at the Information and Tips area. There are probably 10 threads on the first couple of pages related to esata
