Hi all, I've had the same problem. We went to Berlin for a long weekend last Friday 4th October, when we returned our 4000t had frozen up, and after a hard reboot we found that all the recordings that should have happened from Saturday evening had failed due to loss of power. There had been no power cut over the weekend.
Could this be a power supply problem, imminent HDD failure or some kind of alien influence?
Any thoughts?
