Need some more help with 'dd'

Hi there,

I'm trying to copy a (seems to be protected) SD card with GPS-maps on it.
Reason being is that my current original SD card is out of space.

I tried 'dd if=/dev/sdd1 of=tempimage'
and then 'dd if=tempimage of=/dev/sdd1' after inserting the other(larger) SD card.

When starting the GPS with the new card it says that no detailed maps are found.

How can i solve this?
Thanks in advance...

Might just be a card incompatiblity, like trying to use sdhc in an sd slot, could also be the device can't handle the larger capacity card

Have you tried copying from the actual device?
"dd if=/dev/sdd of=tempimage" (note I am not using the partition 1, but the whole device)

You will likely lose some space, but could probably resize it back with gparted.

Only the "maps" are missing? what about the other files?

It appears that an "image" from an old (smaller) media, is of course copied block by block into a bigger media: note down that when it reaches into the second (bigger space) media it remained an "image" of a block device. So, I suggest, create a mount point; locate the image where and what name it is; then mount the copied image to a mount point. Clear the issues of permission, making sure you can execute the mounted folders. Thereafter you can browse into it.

Hope this helps.

Good luck.
