JVC hard disk camcorder GZ-MG21U - problem copying files onto hard drive

I need to copy my video files onto a hard drive. When the video is not connected to my computer, I can see the files, and the menu lets me manage them. As soon as I connect the camera to my Mac, it says USB MASS STORAGE, and I have to manage the files on my desktop, via icon. So I copy the files to the hard drive through my computer, and eject the video hard drive icon at the end of file transfer.

At that point, it looks like the files are erased from the video HD, but they are not. I have to reformat the memory to delete them for real. This is a problem, because it's hard to tell whether I really have memory on the camera HD or not.

What am I doing wrong, or is this just the way it's supposed to be? I don't see any instructions on file transfer of this kind in the manual...

Hi pattywipfler

You can find the user manuals available for this camcorder HERE.

HERE in particular is the instruction manual for your camcorder.

Below are some sections in the manual you may find helpful in answering your questions. I didn't find anything in the manual that was specific to the operating system. However, it does appear that you can clearly identify and safely remove videos and still image from your Camcorder at the device's controls.

"Video Playback" p. 26-29
--> Various Operations during Playback
--> File Search Function
--> To Play Back Files in the [EXTMOV] Folder
--> Deleting a Video File p. 29

"Managing Files" p. 36-37
--> "Deleting Files"
--> "Viewing File Information"

"Managing Files" (Continued) p. 38-39
--> "Protecting Files from Accidental Erasure"
--> "Formatting a Recording Medium"

"Managing Files" (Continued) p. 40-41
--> "Cleaning Up a Recording Medium"
--> "Resetting the File Number"
--> "Changing the Event Registration of Video Files"
--> "Copying/Moving Still Image Files" p. 48

Please, let us know if you have any more questions, etc. We're here to help.

Thank you

I lost the manual and CDs that came with my JVC Everio GZ-MG21U. Am trying to transfer my videos to my laptop using Windows Vista but won't accept it. I need to download the driver. Pls help.


You can download the manual from the manufacturer's web site at
http://books.jvc.com/booklist.asp?Model=GZ-MG21U

You might want to consider NOT using a driver. The best way to download videos and pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy videos and pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any video/photo cataloging program, such as Windows Movie Maker and Windows Photo Gallery.

Deleted footage off my JVC hard disk camcorder Everio GZ-MG30


There is a way to get back those deleted video files from your digital camcorder, BUT it is just possible. Because if those deleted files has been overwritten by new files you saved in, then there is no hope. However usually overwritten cases are hard to happen as long as the hard disk(of your JVC camcorder) has enough volume.

Then, take so called data recovery program to handle the issue and see if you can grab some or all of the deleted files back. Here are some recovery software you may take a try.

If you are running Windows, try this video photo recovery program.
If you are using Mac OS X, turn to this Mac photo video recover software.

You should take care - before your files are recovered, do not save more files to the device concerned(do not take more videos or photos) in case overwritten situation will happen. I hope you good luck.

No you cannot use Hard drive camcorders (any brand) as a web cam. Free software not available anywhere on the web but you can change your movie file extension off your camcorder from .MOD to .MPG then open it with Windows Movie Maker
