Change of SD card

Hey guys, currently i'm using a 1gb sd card with cyan rom installed to my htc dream phone.
If I want to change to a higher capacity sd card, how should i go about doing it? In terms of the applications and stuffs?

Do you have your sdcard partitioned in any way? if its only a fat32 formatted card, you can simply format the new one fat32 and copy all files from the old card to the new. If you have it partitioned, match the smaller partitions on the new card (match sizes of ext 2/3/3 and linux swap if you have one and copy files accordingly) and copy old fat32 stored files onto new one (the fat32 partition size difference should not effect anything). I've tried this myself a few months back upgrading from a 4gb class 4 to an 8gb class 6 and I had no issues. Just be sure both cards were partitioned with the same program if you are using linux [I run Ubuntu], otherwise you may run into admin permission problems

Mine is formatted in the way in this site: http://wiki.cyanogenmod.com/index.php/Full_Update_Guide_-_G1/Dream/Magic32B_Firmware_to_CyanogenMod
So how should I go about doing it?

ext2 partitions on SD card

I'm running Android on an SD card booting from Win mobile with haret.
I've seen people putting 2 additional ext2 partitions (sys and data) on the micro SD card instead of a single large fat32 one.
Can anyone explain the advantages of doing this? Is the system response much faster with this configuration?

Its faster because ext2 is a native linux fs so they acess it faster. Its nearly as fast as nand. I personally make one 256 for system and put data on nand. My card is class 6. If you're running on anything under class 4, it won't make much difference.

Transferring microSD data to a new card (CM 7.1)

I was wondering how is it possible to transfer my existing data from my slow class 2 card to a much faster class 10 card. The actual card is 16GB in size, and the new one should be only 2 GB in size. I have 1 GB ext4 partition and the remaining space is FAT32. The new card should have 1 GB ext 4 and 1 GB FAT32. I know I can format my card in CWM, but is there any way I can move the data and everything to work as before? How can i read EXT4 on Windows and write the data on the new card? Should I use same partition serial numbers when formatting?
If o do a nandroid backup of EXT4, should it restore successfuly on the new microsd?

Solved, made a nandroid backup of sd-ext, swaped cards, copied all from the old fat32 to the new partition, and then used avanced restore for sd-ext.

have you get problem unmount / mount sd card with cm7?, just try it unmount your sd card, and get it out then mount again, and your phone got freezzz

[Q] How to install two android builds?

Hello,
Is there any possibility to run two different android builds on one phone and making it actaully work? Today I am running only an NAND build, but I also want to run an android build from my sd card so I can experiment. I have tried to partition my sd card several ways, but it doesn't seem to work.
I have partitioned a sd card of 2 gb into 1gb of FAT (ubuntu doesn't offer the ability to format into the FAT32 format), 800mb of EXT2 and 100 mb of Linux Swap. And I placed the build I wanted to install (Scooter's Cyanoenmod 7.1) into an andboot folder on the 1 gb FAT partition. But still no succes so what am I doing wrong?
*Also how does one actually switch between the sd card installed and NAND installed android builds?*

set the sd partitions for system and data in atools.
Create 3 partition on sd:
- fat32
- ext3
- ext3
flash the new nbh and then reinstall the new rom.

Migration to new MicroSD Card

im currently buy a 16gb Class10 MicroSD for replacing my 8gb Class2 card, i have a motorola milestone, mi nandroid not have the function to backup ext partition, how i clone my old card to migrate all data and partitions to new card?
I tried to read the information from the ext2 partition with a windows driver without success.
The memory card has 3 partitions, one ext2 (i supposed) bootloader 38mb long, second partition 1,47gb ext2, and last 5,6gb fat32.
The new 16gb card, partitioned in 250mb ext2, 1,46gb ext2 , and 13,7gb aprox. Fat32.
Tried to copy only the info from the fat32 of 8gb card to the fat32 from the 16gb card, and mi apps moved with app2sd dont show in the phone, i suppose the problem is i not copy the ext2 partition from the 8gb card to the new one.
Exist some method like the ancient norton ghost to clone the both cards?
Sorry my bad inglish
