system error turn power off message
 

I'm using a Panasonic AG-HMC 150 and recording along just fine for about 40 minutes when all of a sudden this message appears. I change out my card and resume recording. Everything is fine from this point forward.

However, the video on the card that I was using when the message occurred will not playback on the camera. Was using a 32 gig class 10 card recording in HA mode.

Is the file corrupt? If so, is there a file recovery software or service to recover the lost footage you can recommend?

I haven't tried importing into my computer yet. Anything precautionary I should be aware of before inputting files to my computer?
