JVC GZ-HD40 .. Video Management File Is Damaged?

Hello,

I bought a JVC GZ-HD40 a few days ago brand new.

When I record in Mpeg2 FHD, I get the following error:

"Video management file is damaged, recovery is required to record/playback, Recover?"

This happens at random times into the recording and stops it in it's tracks. I am not concerned about recovery of any footage as I have only been testing.

I have no SD card yet ,so I record straight to HDD..

I haven't tried anything because I don't know what a video management file is, I also don't understand how it could be damaged as I have not done anything but point and shoot, and have only ever cradled it lovingly- so far!

Any help would be very appreciated as I dont want to send it back if it is my fault through lack of experience.

PS, I didn't format the drive before use?!? Could this be it.

Many Thanks in advance..

Mark.
