I have been using an external 1 TB ESATA drive in the Antec MX-1 enclosure and I have had to reboot the HR21-700 DVR several times to "fix" problems. Tonight the Guide was stuck on date 7/14 (weird) with no program info. Have no idea how or why this happened. I pressed in the Red Reset button for several seconds and after the HR21-700 came back up ALL of the recorded programs were gone (List is empty) and the DVR settings were ALL back to factory defaults. Rats@!!! Does the Red reset button always erase the recorded List content?? Did I hold down the reset button to long and thus got a complete reset or something?? What is the BEST way to reboot the DVR and NOT lose the recorded programs on the external ESATA drive?? I do have a UPS for both the ESATA external drive and the DVR. Is it best to power down the common UPS (powering down both ext drive & DVR at same time), and then turn UPS back ON to restart everything? Is this the way to NOT lose my recorded stuff and custom DVR setup info? Please help. Thanks!!!
