JVC Envirio GZ-MG21U Error Msg.

I had the same issue, but I went ahead and executed the recovery and my videos were still there. I thought I had lost one but it was actually saved/loaded to another image file in the camera which is the same one that the Demo playback file is stored in. I located it by connecting the camera to the PC going under my computer and just opening every file. After I got everything off the camera I went into the menu and executed the data clean up program. I am now scanning internet sites to see if there is a fix listed anywhere to keep it from happening again. Hope this helps.

Every time i upload to my desktop i delete the videos off the camera threw windows xp.

EVERYTIME i turn it on after it says that "video file broken blah blah"
i hit ok and it takes a min. but worked ok after wards.

Every get the auto drop shut off thing? i got that once and camera didnt turn on for months. after 3 months of sitting inside it decides to work 100% !! the 2nd time the camera did that the hard drive says its full so i cant record, i go to look at files and it says "no video files found" followed by a very ironic "hard drive is full"
i've only had it for 2.5 years but 1.5 years after warranty.
the worst part is I NEVER DROPPED THE CAMERA IN THE 1st place.. and when i did this auto shut off thing sure as hell didnt work. jvc has no comment on this as its after warranty.
hopefully in another 3 months i will try again and it will work 100%
