Charts on SD card???

I thought I'd be clever and make a back-up in case I lost the original or it got corrupted or something. So I copied the original to the new, blank SD card using my laptop which has the port for various cards including the tiny SD card and it copied successfully according to the laptop and Windows Explorer shows the proper files and size copied but it doesn't work in the GPS. I Googled it and found out that somehow the files won't open on any SD card but the original because it's somehow coded to decrypt only in the presence of the hardware ID of the original card. So the question is this: Does anybody know of a way to reprogram a blank SD card's ID so it matches that of the ID of a digital chart SD card? I think they call this a 'crack?' One ought to be able to make a backup copy of software he has bought and is licensed to use . . . Wilbur Hubbard If you use Unix or Linux there is an application called "dd" which is said to be able to make a byte by byte copy of an disk, directory, file, whatever. It might work. Cheers, Bruce |
