Backup on . android_secure - Missing Apps on MicroSD I Have been Backup and Formatted my MicroSD. After then I Copy again my backup files, But  - Apps on MicroSD is  Disappear, I check on Application Manager its Still There but not show in menu drawer.
As I read related Question on Upgrade SD Card, I Tried to copy all files with command prompt/by windows. But I confuse how I backup on .android_secure that have all asec apps on micro sd. I copy via card reader/usb. its fine, when media scanning running, i check on that folder again an all asec is missing. anybody knew the alternative method on this problems.?
I Use Galaxy Ace on Gingerbread (2.3.3) with Class 10 8GB MicroSD.
Thanks lot. :D
MicroSD is generally hot swappable (unlike SIM card), but this thing screws things up.

First, turn off the device. Remove old MicroSD. Clone it including .android_secure. Insert new MicroSD while device is off. Then, boot the device.
