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

  • Can you clarify what you're asking? If you didn't backup .android_secure there's not much we can do to help you with that. Windows should copy folder beginning with . just fine, unlike some Linux tools. Use Explorer if the command line is finicky. Apr 19, 2012 at 1:26
  • @Matthew He has copied .android_secure, but its not reflected back in device. Once I also faced the same problem with my Galaxy S.

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.
