clone of a Navi-SD

Hi everyone,

I will make a clone of a navi-sdcard for backup from the original.
I can copy the card but the copy will not work.

Anyone an idea ?

It is a navi-sdcard from VW ...

I have copy the master-sd-card to a empty sd-card.
Thats no problem but the Discover media plus - device from VW don't recognize that card.
Someone says to me that it's is because there is a hidden secured partition on the SD-card ?
anyone here experience to read/view hidden secured partition on a SD-card?

Tim.

How did you make the clone ?

Hi,

I make a 1:1 clone with DMDE.

Just a guess. Maybe the problem is not with the cloning but with the sd card serial number. Copy protection?
