Since I assume this issue would relate to both the JVC and Sony full HD 3D camcorders, hopefully someone has already found a simple solution for making multiple full HD 3D copies on more than one external media device. With the Sony I am able to download 3D video onto a USB connected external hard drive without any problem. However, when I try to hook up a second USB connected hard drive the camera recognizes that I have already downloaded the 3D (and all other) files that were on the camera's hard drive and will not let me do it again on a separate external hard drive. (The files are still on the camera's hard drive.) Is there a work around to accomplish what I am trying to do by simply somehow telling the camera that I want it to repeat the original download to a second USB connected external hard drive?
The advantage of having the same data on two different external hard drives is not only for back-up but also I could then just mail the small hard drive to someone else who has the same camcorder and they could attach it to their camcorder and see the 3D videos I have taken without my having put them into a compromised format that degrades the resolution or reduces the bit rate. You can now get a 750 GB USB connectable hard drive for close to $50.00 - the price of a 16 GB SD card.
