Is it possible to recover lost video files from a digital camcorder?
Back in November, I shot some amazing footage from ~300ft up while parasailing, and it was saved to the internal memory of my Aiptek digital camcorder. But when I got back and looked for the footage, it just wasn’t there. I think one cause may be that I dropped the camera at one point. But is there anyway that I could recover the files? Could I take it to a computer repairman or something? I really loved that video.

yes.. use a software called card recovery…
If you have recorded on the videos then you probably can’t. http://www.recuva.com
