External HD reverts to internal must reboot to get back

[jdspencer]

May I suggest that you put the DVR and eSata on a UPS. It's just good insurance against power outages. And if the outage is longer than the battery lasts, it will power up when the power returns to normal parameters.

Good advice. I found that going back to my series 1 tivo days and through my current HR20 days, that I have far fewer 'weird' problems when I put the receiver and any external connected piece parts like disk drives and SWM or long run amp power supplies on a small UPS. I find deals on them at the office supply stores for $10-25 for the very small ones. They'll only run for about 5-7 minutes on the little UPS's, but thats good enough to cover for voltage sags and momentary glitches.

I've found that all the dvr makers use cheap power supplies, and if the voltage sags much under 100v they keep running, but do lots of weird things like lose the network or modem ability, stop responding to the remote, etc. Some of the weird stuff is persistent even after the voltage comes back up to normal.
