Re: Some bad files, not readable

First, there is a clip repair function to salvage the clips. It's in the user manual. Second, the reason this happened in the first place is because you've probably never done a MEDIA DUMP of your cards. That is also in your manual. If you don't do a MEDIA DUMP regularly then what I call "dirty file fragments" build up on the card and eventually can damage recorded clips. Simply deleting clips or formatting the card is not enough. A MEDIA DUMP wipes EVERYTHING off the card. Sony suggest doing this everytime you delete media from the card. I actually do it every few weeks and have never had a problem. In your case, if you don't dump soon, you'll eventually have your camera crash on you during recording which will permanently damage the card. You should always read through your user manual carefully before using a new camera.
