[Q] SD Upgrade Problem?

---

I've got a problem with replacing the SD card. I searched for it and it seems like no-brainer. But I don't know what the problem is:

I bought a 16 GB Transcend to replace the SanDisk 2GB that came with my Liquid.

I have [Leaked]Froyo ROM. I had many apps on SD and some on the phone.

Here is what I did:

- I unmounted the 2GB card in my phone and turned it off.

- I put the new card and turned the phone back on.

- Then connected the old card with a card reader to my Mac. Also, connected the phone via USB and turned the USB storage on.

- I just copied everything from the old card to the new card and turned the USB storage off.

Now here's the problem:

None of the apps on SD are working! And they are not linked! It seems they are not installed.
When I tap their home screen icons, I get the error: "The application is not installed on your phone"
Also, only the apps on the phone are shown in applications.

I double tried the same process with formatting the new card in the phone, but got the same thing. I also copied the hidden folders as well. No luck with that, too.

Any suggestions? It is really driving me ...

BTW, I put the old card back and it is working just fine.

Problem Solved!

I finally found out what the problem was and upgraded my microSD successfully with all the applications working.

I decided to post the SOLUTION so it may help others as well:

The key issue is in the .android_secure folder on the SD card. Before this, I didn't know it is the place where Froyo puts all the apps that are transferred to SD.

Here are the steps that worked for me:

1) Unmounted the old SD and turned the phone off.

2) Copied EVERYTHING from the old card to my PC (I used a card reader).
**ATTENTION: By everything I mean all the files and folders including folders starting with "." (Especially .android_secure)

3) Formatted the new card (FAT32) using the Windows.
**FOR CAUTION: DO NOT use the phone to format the card. Because it makes a .android_secure and it will screw with the one you want to replace. [If you have done it anyways, just make sure to REPLACE the .android_secure folder]

4) Connected the new card to the PC and paste everything to it.

5) Put the new card in to the phone and turn it back on. BINGO! All should work without any problem.
