I'm currently having the exact same problem and my files cannot be read by a card reader either. I have 500 photos of my holiday in India on there so I'm desperate! Did you find a solution?

There is a tiny slide switch on the side of the memory card if you look on carefully. Slide it accordingly as indicated to unlock, this is provided to prevent accidental erasure of important data in the card.

Don't know about cam (was there a software disk to install?).
As far as the reader goes you reader must be compatible with both devices.
Hope this helps

Try to recover what is left on the memory stick with TestDisk on a pc.
Note, download the windows version and not the dos/windows version, the
dos/windows version is for windows 3.11 and lower.

Format memory card through Format option in camera Menu, this will delete all files on memory card and will refresh it.

Yeah there is an issue with the format of the card, you would need to format the card before you use it ever in your camera or pc.. The thing is people think there already formated and the camera sotred the pics on it without a format or with a format of its own that is not recon. by the computer. Make sure you format using FAT and not NTFS or any other format to allevaite further issue's..

Connect the memory card/stick to a USB memory card reader and then plug it into the USB port in the computer. The computer will see this as an external memory card.

does ur camera recognize ur mem stick if yes then copy all ur pics to a computer then format it an insert the stick to ur cam and u can copu it again to the stick. check it out.

The possible cause of issue is file corruption or virus infection, scan your MMC cards for any virus infection or format it using the device in which you use it.

There are plenty of undelete tools around.

Please check the menu, to see after what time the cam should stop. Also check the battery. Bad battery will also cause a dashcam to go in sleep mode.

Just google "rescue my files" Lots of sites are offering software to recover deleted files, or even files from a formatted drive. Be aware, if you did write anything on the drive after formatting, it will decrease the chance of and the amount of files you can rescue. Most sites offer a trail version wich you should use first, to see if there is still something to rescue. To my knowledge there were some good freeware programs, but not sure they are still there. I use a paid version, since I deleted a drive by accident

The LCD does not have the program to read the files so have the flash in a computer and change the file type. fore media you should select even one of the files and click on options then select restore to previous version the on the pop-up change the medai player where it says change with the icon on it. it will let you choose another media of your choice.

it is a USB flash drive like ant other USB flash drive or memory stick
