Hi, I am new to this forum and I am not sure if my question will be right in this forum or not. I am trying to back up the whole image of SD data but I am unable to do so. Is there any software similar to DVD ripping somewhere? The reason is I have this Hard disk Car navigation(Panasonic) and the new Map is available in DVD with SD card. The trick is that Only once the SD is used for upgrading your map, the contents of the SD seemed to be changed and you can not upgrade the other navigation(I have another in my wife's car). So, I have to do the followings: 1.The SD card before restoring back to the original, need to be duplicated including format and everything in other SD card. 2. With #1 above SD card, retore back to original data and try installing my other car navigation. Does anyone knows any software that does all? Pls help, if I am posting this here is not right Pls refer to appropriate forum. Thank you so much your kind help.
