No it is file system corruption. If you desperately want to retrieve the recordings this can be done by connecting the drive direct to a PC and using humaxrw in recovery mode. The fix for the problem is to format the disk from the HDD control menu which takes only a second or two. If the problem reoccurs quickly then it may indicate that the disk is failing.I switched on the box only to find all my recordings had gone. There are no error messages. I did an instant record and it appeared in the list, but when I played it back it was just black. It then disappears from the list when the box is restarted. Is this hard drive failure?
This is a common problem and I don't think anybody has provided a good explanation of what causes it. My own theory is that there is more than one cause but I have no real proof.PS We have had quite a lot of thunderstorms in the north east recently. I wonder if that could have caused the problem?
