Apps missing after upgrading sd card I have been searching for how to properly upgrade to new sdcard, and I did as this posts suggests. How to upgrade / swap SD card without losing data and installed apps?.

But when inserting the new sd card several apps (not all) are missing. I had about 80 apps installed, could that explain why I am having this problem, while no other seem to have it?

Could it be, that there are two partitions on the original sd card, one being used for apps when internal memory is full; and I have then only copied the part not in the 'simple' partition?

Using Gingerbread (2.3.3).
I found out that all the apps missing have an .asec file in the .android_secure folder on the sd card, however the .android_secure folder itself is there. 

On Linux I wrote:

cp sdbackup/* /media/disk -r


It copies all folders, and their content, recursively. Except for the hidden folders in sdbackup, e.g.:

sdbackup/.android_secure
sdbackup/.doubleTwist


Hidden folders in the hierarchy are copied however. 

So now I managed by subsequently copying each hidden folder:

cp sdbackup/* /media/disk -r
cp sdbackup/.android_secure* /media/disk -r
cp sdbackup/.astro* /media/disk -r
etc


And now everything is fine.
