Have an Onkyo TX-DS898 A/V receiver (doesn't have HDMI) connected to DVR7232 via component cable + optical cable. A Verizon-recommended Western Digital e-Sata drive is connected to the DVR. Each component worked together without difficulty for several months.
Due to unrelated DVR failure, have replaced the DVR twice in last few weeks. Have performed the "enable more storage" routine many times, formatting the expansion drive each time. The expansion drive is recognized and shows as 100% available.
Once the A/V receiver is turned off, the DVR shows the time for about 5 seconds, then reboots. I have tried powering off the TV, DVR and A/V receiver in different sequences with the same result. I've done this so many times that every so often, the reboot doesn't occur for several on-off cycles, then it starts rebooting again. If I disconnect the e-Sata drive the reboot problem goes away completely.
Any suggestions will be much appreciated.
